ABAP Cloud LoggerABAP Cloud LoggerWraps ABAP Cloud's cl_bali_* Application Log classes in ZCL_CLOUD_LOGGER, an open-source, MIT-licensed logger installed via abapGit. One fluent entry point takes free text, sy-msg-style messages, exceptions, BAPIRET2 tables or arbitrary data serialised to JSON, and multiton instances keyed on object/subobject/external number let unrelated code share a logger without passing instances around. It adds sticky per-iteration context, built-in timing, and a readable trail of the cx_bali_runtime errors the class swallows internally.Greltel, published 2026-04-30
Authorization management with OpenSearch's Document Level Security - SAP Cloud LoggingAuthorization management with OpenSearch's Document Level Security - SAP Cloud LoggingWhere the predecessor SAP Application Logging service reused CF space permissions for read-only access, SAP Cloud Logging integrates with SAP Cloud Identity Services (IAS) and controls per-document visibility through OpenSearch's Document Level Security: an IAS group becomes a backend role, mapped to an OpenSearch role that carries a DLS query filter, so a search request only ever returns documents whose indexed field (space_name, organization_id, or another keyword field) matches what that role's filter allows. It walks through fixed per-space roles, a shared multi-space role using a terms query, and a single dynamic role that substitutes ${user.roles} into the filter so the match is against the caller's own groups, then lists operational pitfalls — wildcard index patterns breaking Dashboards, DLS roles that also hold write access creating log entries nobody can read back, and match queries against a .keyword field being non-deterministic where term queries are exact.Hariharan-Gandhi, published 2025-11-24
Capturing Background Job Errors in SAP Using the Application Log (SLG0/SLG1)Capturing Background Job Errors in SAP Using the Application Log (SLG0/SLG1)Walks through ABAP's Application Log framework for recording errors from a background job that has no screen to show them on: defining an Object and Sub-object in SLG0, then building the log in code with BAL_LOG_CREATE, adding a free-text or message-class entry with BAL_LOG_MSG_ADD_FREE_TEXT or BAL_LOG_MSG_ADD, and persisting it with BAL_DB_SAVE so it survives after the job finishes. The worked example is a report inserting student records into a custom table, scheduled via SM36 and reviewed afterwards in SLG1, filtered by the Object and Sub-object that created it.bhuvaneswarg, published 2026-08-26
From Application Logging to Cloud Logging: Service Innovation GuideFrom Application Logging to Cloud Logging: Service Innovation GuideSAP Cloud Logging replaces SAP Application Logging service, moving each customer from a shared multitenant stack to a dedicated, fully isolated one, and this guide sets out what changes with the move: a deployment per compliance region instead of per Cloud Foundry landscape, SAML/IDP-based authentication instead of Cloud Foundry-bound auth, retention that is configurable instead of fixed at seven days, and hourly capacity-unit pricing instead of fixed-size monthly plans. It also states the deprecation timeline for logging on BTP: SAP Application Logging closes to new or renewed CPEA contracts after 2025-07-31, while contracts signed before that date keep their entitlement until their next renewal.Hariharan-Gandhi, published 2024-11-22
From Application Logging to Cloud Logging: Service Migration GuideFrom Application Logging to Cloud Logging: Service Migration GuideA six-step guide to moving off SAP Application Logging service for SAP BTP onto SAP Cloud Logging: plan the instance layout, set up an Identity Authentication Service tenant for single sign-on to the new service, bind applications to both services in parallel so log data flows to each for comparison, then deprovision the old service once Cloud Logging holds the retained history. It covers what the logging libraries need so custom fields reach both services during the overlap: the CF Node.js library detects both bindings itself from v6.5.0, while the CF Java library has to be configured to retain each custom field at top level. It also gives the deprecation date SAP published for Application Logging under CPEA contracts, 31 July 2025.Hariharan-Gandhi, published 2024-11-22
How to Access SAP Cloud Logging Service Dashboards Using IAS SAML AuthenticationHow to Access SAP Cloud Logging Service Dashboards Using IAS SAML AuthenticationWalks through wiring SAML 2.0 single sign-on between SAP Cloud Identity Services (IAS) and SAP Cloud Logging so its OpenSearch dashboards accept IAS logins instead of a service key: creating the SAML application in IAS, editing the instance's saml parameters (admin_group, idp.metadata_url, idp.entity_id, sp.entity_id), setting the matching entity ID and endpoints on the IAS side, and mapping an IAS group to the all_access role through a groups attribute. It also shows how to read a 403 on the dashboard as SAML login succeeding while the group-to-role mapping is still missing.Umezuki, published 2025-12-30

Instance Sharing - SAP Cloud LoggingInstance Sharing - SAP Cloud LoggingExplains how to share one SAP Cloud Logging instance across Cloud Foundry spaces, subaccounts and regions instead of provisioning one per space, contrasting built-in platform sharing, where credentials are transferred automatically but the scope stays narrow, within a single subaccount in the post's own example, with reusing a service key through a Cloud Foundry User-Provided Service, which applies across regions, subaccounts and environments but leaves credential transport and rotation to the customer. Walks through a cf share-service example and the cost, legal and ingestion-throughput tradeoffs against dedicated instances.Hariharan-Gandhi, published 2025-08-13
Kyma Integration with SAP Cloud Logging. Part 1: Introduction and shipping LogsKyma Integration with SAP Cloud Logging.

Migrating from Application Logging Service to Cloud LoggingMigrating from Application Logging Service to Cloud LoggingWalks through migrating from SAP Application Logging service for SAP BTP to SAP Cloud Logging on Cloud Foundry: sizing instances against the two services' quota and retention differences, running both bound in parallel for a week so no logs are lost, adjusting the Java and Node.js logging libraries' custom-field configuration so entries reach both, setting up SAML sign-on through IAS, and deprovisioning the old instance once Cloud Logging is confirmed to receive everything. Superseded by a newer version of this post; the quota math, custom-field steps and deprovisioning sequence here still hold.bill_keyes, published 2023-12-19
Migration Journey from MuleSoft to SAP Integration Suite (CI)Migration Journey from MuleSoft to SAP Integration Suite (CI)Maps MuleSoft Anypoint's error handling onto SAP Integration Suite: the Global Error Handler and MuleSoft's built-in retries become Exception Subprocesses with scripted Groovy retry logic or JMS-based retry, since Cloud Integration has no automatic equivalent. MuleSoft's searchable logger text becomes Content Modifier headers and Groovy-scripted Message Log entries, correlated by application message ID and correlation ID for traceability across complex interfaces. The mapping is drawn from the author's own migration project across assessment, development and validation phases, and is explicitly flagged as not an SAP- or MuleSoft-approved design.Shailaja, published 2025-09-21

SAP API ManagementのアクセスログをSAP Cloud Loggingで可視化する方法SAP API ManagementのアクセスログをSAP Cloud Loggingで可視化する方法In Japanese. API Management's own screens show call counts but not the individual request log — no audit trail, no header or IP detail, which leaves auth failures hard to diagnose. The author's fix is an API Policy that builds a structured log entry with AssignMessage and forwards it through a syslog drain to SAP Cloud Logging, and confirms the ingest endpoint works by PUTting a test message to it directly with Postman before wiring the policy.yasuyukiuno, published 2025-09-24

Container metrics for a CAP Node.js application into SAP Cloud Logging Service, and the reason it exists is that the obvious route does not apply: Spring Boot Actuator covers the Java side, and Node has no equivalent, so the author reaches for Telegraf instead.

Unleashing ABAP Potential: An introduction to Extension Libraries (XCO)Unleashing ABAP Potential: An introduction to Extension Libraries (XCO)Introduces ABAP's Extension Libraries (XCO), a library framework that puts reusable functionality behind one interface. The post places it as part of the ABAP RESTful Application Programming Model but versatile enough for other ABAP contexts, and says it works in both on-premise ABAP and the ABAP environment on SAP Business Technology Platform. It walks through a worked Logging example: xco_log=>factory->create_new_log opens a log keyed by object, subobject and external ID, logger->add_message appends a typed message, and logger->add_last_symsg attaches a problem class and level of detail for later traceability.tamitdassharma, published 2024-11-27

UI Composition with Application Frontend ServiceUI Composition with Application Frontend ServiceWhy shared UI code is hard, and what Application Frontend changes about it. The piece first lays out the three usual answers and what each costs — copying files at development time and repatching every consumer, publishing an npm package and rebuilding every consumer, or hosting the code separately and paying for it in CORS and session handling, or in an extra network hop through a server-side proxy. It then shows a fourth that only this service can do: runtime server-side composition without the hop, configured through routes in the consuming application's xs-app.json, across three cases — a reusable application embedded in a consumer, and two further composition shapes. Read alongside the generator, which scaffolds the mta.yaml, xs-app.json and zipper configuration this model needs.Vadim Tomnikov, published 2026-05-18

It runs on abap-adt-api, the same REST client Eclipse's own ADT tooling uses, and sits beside SAP's own ADT MCP Server, shipped with ADT for VS Code and Eclipse under a different server key, and marianfoo's abap-docs, a read-only server over the ABAP Keyword Documentation and Clean ABAP. Each destination carries a policy — read-only, allowed packages, denied tables and tools — the server checks before every call, and an optional audit file logs each tool call with its outcome and policy gate.Willian_Saez, published 2026-09-03

S/4HANA公有云版的内部ABAP拓展S/4HANA公有云版的内部ABAP拓展Argues that S/4HANA Cloud public edition's in-app ABAP extensibility is still real ABAP development, just under stricter rules: developer extensions require ABAP Development Tools rather than SAP GUI transactions, data models are defined as CDS views instead of SE11 tables, business logic is a RAP behavior definition instead of a function module, and service exposure is an auto-generated OData service from a Service Definition instead of a hand-built RFC/BAPI.

Getting there means learning that HANA's fuzzy .search() matches one word but not a full sentence, fixed by splitting the query into terms and merging the per-term hits, and that provisioning SAP HANA Cloud hits a database-level free-tier quota rather than an HDI-container one, with a stopped instance needing to be resumed first.

SAP Cloud Application Programming Model（CAP）：概要およびデモ - Part 1SAP Cloud Application Programming Model（CAP）：概要およびデモ - Part 1Introduces SAP Cloud Application Programming Model as an open, opinionated framework that shoulders OData plumbing and database-specific code so a domain is modelled once in CDS, then builds a small bookshop project to show it: @sap/cds-dk's cds init scaffolds the project, cds watch serves it locally with live reload against an in-memory SQLite database, and a CatalogService projects a CDS domain model seeded from CSV files. The result is read as an OData service in the browser and exercised further through a Postman collection, with the optional @sap/vscode-cds extension noted for CDS syntax highlighting and completion in VS Code.rasai, published 2020-12-31

Surviving and Thriving with the SAP Cloud Application Programming Model: Local development hurdlesSurviving and Thriving with the SAP Cloud Application Programming Model: Local development hurdlesThree hurdles in running a CAP application locally: services mocked with cds run --with-mocks return no data across OData associations until the ON clause is hand-written into the imported CDS, an on-premise API reached through the SAP Cloud Connector times out because its proxy is part of destinations and connectivity and reachable only from inside SAP BTP, and a Fiori frontend served from the HTML5 Application Repository needs the HTML5 Repo Mock to reach a local backend at all. It closes with the launch configurations the author uses for debugging cds watch locally and attaching to a running Cloud Foundry instance.maxstreifeneder, published 2023-02-02

Diagrams related to OData entities (CAP & ECC)Diagrams related to OData entities (CAP & ECC)Builds a small CAP service that uses the framework's reflection API to read an OData entity's elements and associations and emits PlantUML diagram source for it, as a hand-rolled alternative to the OpenAPI/Yuml-based diagram export capire documents. The author contrasts the PlantUML result with the OpenAPI/Yuml diagram, calling it more detailed and giving more control over orientation, colors and links. Part 1 of a two-part series; part 2 covers the same idea for ECC/ABAP.Pierre_Godart, published 2022-09-06
BTP CAP : Custom plugin to separate generic change log capture logicBTP CAP : Custom plugin to separate generic change log capture logicWalks through building a custom [CAP](ecosystem:cap) plugin that centralises change-log capture: on cds.once('served') it collects entities annotated @audit, then hooks srv.before('UPDATE') to read the existing record, diff it field by field against the incoming payload, and record old/new values with the user and timestamp. It also documents a cds build failure packaging the plugin's own directory into gen/srv for MTA deployment, fixed by adding it as a copyfiles build-parameter step in mta.yaml.sreehari_vpillai, published 2023-05-10
Create your first CAP pluginCreate your first CAP pluginA step-by-step guide to the cds-plugin.js extension point: scaffold a package, add an index.cds for shared model artifacts, and test it locally against a throwaway CAP project before publishing to npm, with a separate section on building the same plugin in TypeScript and compiling it with tsc. Points to the author's own cds-plugin-handlers and ui5-cap-serverside-rendering-plugin as worked examples.published 2024-12-09
How to build reusable plugin components for CAP Java applicationsHow to build reusable plugin components for CAP Java applicationsA companion to Daniel Schlachter's Reusable components for CAP with cds-plugin, showing the same mechanism on CAP Java: a plugin ships as its own Maven artifact with an event handler and a CdsRuntimeConfiguration implementation, registered through the JDK's ServiceLoader rather than any CAP-specific wiring. The walkthrough builds a cds-emoji-plugin-java jar that decorates @emoji-annotated fields on read, installs it to the local Maven repository, and adds it as a runtime dependency to a cds init --add java bookshop application. It argues the plugin mechanism was not new to CAP Java, just previously undocumented.robinjayasinghe, published 2023-05-16
Reusable components for CAP with cds-pluginReusable components for CAP with cds-pluginThe post that taught the mechanism, and it teaches it by picking a requirement small enough to be absurd: every string a service returns should end in a random emoji. Working through that on the bookshop example leaves nothing to argue about except the plumbing, which is the point — what a cds-plugin is, where it hooks in, and why packaging it beats copying it into the next project. Vinícius Barrionuevo credits this post as the thing that gave him the idea for sap-cap-sdm-plugin, and it is hard to read the plugin ecosystem in this graph without it.published 2023-04-30
SAP AI Services - DOX - Gen AI with SAP CAP Plugin - Part 3SAP AI Services - DOX - Gen AI with SAP CAP Plugin - Part 3Building on Reusable components for CAP with cds-plugin by Daniel Schlachter, this part walks through a custom CAP plugin — a cds-plugin.js plus a lib_cap_dox.js helper — that authenticates against SAP's Document Information Extraction (DOX) service and calls its schema and job-status APIs to fill an entity from extracted document fields. It covers reading the service key from Cloud Foundry (cf service-key) for the OAuth token endpoint, and dynamically mapping DOX's header and line-item output onto CAP entity properties.sabarna17, published 2024-06-11
A Handy Custom Report to Scan SAP CDS Views for Usage of Search StringsA Handy Custom Report to Scan SAP CDS Views for Usage of Search StringsA custom SE38 report, ZSCAN_CDS_VIEWS, reads each Z-prefixed CDS view's DDL source through the function module /ABEX/SEFW_MOD_CVA_HANA and scans it for a list of search strings, listing the view and matching code line in an ALV grid. The author built it because ABAP Development Tools for Eclipse's ABAP Source Search, the code search SAP ships, is unwieldy for scanning many custom views at once or searching several strings together.shasankgupta024, published 2026-01-08
Add useful Extensions to Dev spaces in SAP Business Application StudioAdd useful Extensions to Dev spaces in SAP Business Application StudioStarts from the point capire makes — that CAP is editor-agnostic and BAS is the preconfigured option — and then does the thing that undoes preconfiguration: adds two extensions to a dev space for initialising data in a CAP application, with the uninstall procedure as well as the install. The uninstall half is what makes it worth keeping.showkath_naseem, published 2022-11-13
Avoiding Data Loss When Loading Initial Data with CSV Files in CAPAvoiding Data Loss When Loading Initial Data with CSV Files in CAPcds add tiny-sample gives you a CSV in db/data and it loads on deploy, which looks like a way to seed a productive application. The catch, stated plainly: change the CSV or the schema and HANA is reinitialised from the file, taking whatever users had entered with it.MioYasutake, published 2025-09-15
CAP: Consume External Service - Part 1CAP: Consume External Service - Part 1Builds a CAP Node.js service from scratch that consumes the public NorthWind OData V4 service: cds import turns its EDMX metadata into a CSN model under srv/external, and a CatalogService projects Products from it with a custom READ handler that runs the request through cds.connect.to('NorthWind'). Shows the same projection working two ways — against a CSV mocked under srv/external/data with the <service>-<entity>.csv naming the framework expects, then against the real service once credentials.url is added to the CAP configuration and @sap-cloud-sdk/http-client is installed — and defers routing that connection through the Cloud Foundry Destinations service to the next post in the series.published 2020-05-26

Random Numbers and Probability Distributions in the ABAP Environments for 2508Random Numbers and Probability Distributions in the ABAP Environments for 2508Introduces CL_ABAP_PROB_DISTRIBUTION and CL_ABAP_PROB_DISTRIBUTION_DF34, new ABAP system classes that generate random numbers from a distribution — normal, lognormal, exponential, gamma, chi-squared, Poisson, binomial, Student's t, hypergeometric, geometric — rather than only the uniform spread CL_ABAP_RANDOM gives. The worked example builds customer payment dates clustered around a due date instead of spread evenly across it, which is the shape seed data needs to look real rather than merely present; the same classes also compute CDFs and quantiles for statistical tests like a t-test on payment lateness. SAP plans this for on-premise and the private cloud with the 2025 major S/4HANA release, subject to change.kilian_kilger, published 2025-08-18
Using the UI5 Mockserver for Client-Specific Data and TestingUsing the UI5 Mockserver for Client-Specific Data and TestingWalks through a same-day feature in @sap-ux/ui5-middleware-fe-mockserver, 'Support autoloading mockdata file for specific tenants', which loads a <Entity>-<client>.json file keyed to the sap-client URL parameter and falls back to the entity's plain JSON file when no client-specific one exists. Shows the setup replacing generated mock data with hand-written JSON, then drives the same sap-client parameter through separate package.json scripts so wdi5 end-to-end tests can run against distinct tenant datasets.published 2024-11-18
Claude ported ABAP functions to new APIClaude ported ABAP functions to new APIA first-person account of using Claude Code, driven through the sapcli command line, to install and repair RFC function modules that let a CI pipeline control abapGit and gCTS remotely, rather than treating git as a way to read ABAP source. Instead of trusting a local checkout, Claude read the abapGit login manager class and queried the target system's own type catalogue through sapcli, then used what it found to update a renamed API method and swap a TABLES parameter's structure for the table type BAPIRET2_T.jakub_filak, published 2026-03-16

Taking Control of Clean Core: When to Use Project Kernseife in addition to Standard SAP ToolsTaking Control of Clean Core: When to Use Project Kernseife in addition to Standard SAP ToolsWalks through how SAP's standard path classifies custom ABAP extensions into Clean Core Levels A through D, running ABAP Test Cockpit against the Cloudification Repository's release status for each SAP object an extension touches, then feeding results into the RISE with SAP Methodology Dashboard in SAP Cloud ALM. Contrasts that with Project Kernseife, an open-source custom ATC check that lets a team override SAP's classification with project-specific rules, define its own successor objects (including custom wrappers), and expose a Score and Potential Score per finding through a CDS view for prioritizing cleanup — at the cost of owning and maintaining that classification. States which situations favor each: Kernseife where the standard rules are too rigid for the project's reality, the standard dashboard where cross-system comparability and low maintenance effort matter more.LBretschneider, published 2025-11-04
