Federated Machine Learning with SAP DatasphereFederated Machine Learning with SAP DatasphereSAP's design for training predictive models on an external machine learning platform against SAP Datasphere data that is not replicated to that platform. The open-source FedML Python library runs in the platform's notebook, connects to Datasphere over Python/SQLDBC and reads the analytic models in which Datasphere unifies SAP and non-SAP sources; a trained model can then be deployed to SAP AI Core, or in several sub-pages to SAP BTP, Kyma runtime, which is the predictive models path where training happens outside SAP. Sub-pages cover Amazon SageMaker, Azure Machine Learning, Google Vertex AI, Databricks, NVIDIA RAPIDS on GPUs and IBM watsonx.published 2025-01-23
Building an Attachment Upload and Download Solution Using UploadSetwithTable ControlBuilding an Attachment Upload and Download Solution Using UploadSetwithTable ControlThe successor control to UploadSet posts the file in one request by default, and against CAP that is wrong: the record has to be created first and the content put to it afterwards. The author states the two-step shape plainly and notes it may not apply to an ABAP backend, which is the kind of boundary that usually goes unsaid. Written during a proof of concept for a reusable attachment component, and it carries the problem they hit with the control.published 2025-03-13

Boosting performance in SAP Cloud Application Programming Model (CAP) applications with cds-cachingBoosting performance in SAP Cloud Application Programming Model (CAP) applications with cds-cachingThe plugin's introduction post: what cds-caching is for, how it is put together and the cases it was written against. The edge holds because the plugin's README still points here as the piece to read first, so this is where a reader arriving at the plugin is sent. It predates version 1.0 and the API has moved since: the read-through calls it shows as cache.run() and cache.send() are the ones the README now lists as deprecated in favour of cache.rt.*, which returns the cache key and hit/miss metadata alongside the result, and 1.0 made user, tenant and locale awareness opt-in under keyManagement rather than folding them into request-based keys by default. Metrics and monitoring, the OData API and full TypeScript definitions arrived with 1.0 and are described in CAP just got faster: What's new in cds-caching 1.0 instead. The reasoning about when a CAP service wants a cache still reads true; the call sites need translating.published 2025-06-25

CAP just got faster: What's new in cds-caching 1.0CAP just got faster: What's new in cds-caching 1.0What changed in cds-caching at 1.0, announced at reCAP 2025 by the plugin's own maintainer. The substantive change is the read-through API: cache.rt.run(), send(), exec() and wrap() replace the bare cache.run() and cache.send(), and each returns the cache key and hit-or-miss metadata beside the result rather than the value alone. The second is quieter and easier to miss on an upgrade: user, tenant and locale stopped being folded into request-based cache keys by default and became opt-in through keyManagement, or per operation through a key template. Both of those still describe 3.x. What does not is the second half of the post: the metrics configuration it shows was reshaped at 2.0 and the statistics and dashboard settings were removed at 3.0, so take the monitoring and dashboard sections from the README instead. Read it as the successor to the introduction post, which still shows the deprecated calls.published 2025-07-15

Clean Core IndexClean Core IndexDescribes a company-built KPI, the Clean Core Index, that scores existing custom ABAP code by object type — reports, function modules, SAPScript/Smartforms, ATC S/4 readiness-check findings, user exits and modifications — each weighted by a severity the author sets for redesign effort and upgrade risk, with counts read off CDS views built for the purpose. The index is the author's own definition rather than an official one and does not by itself certify public-cloud readiness, but tracking it weekly shows where custom code still blocks a move to ABAP Cloud and lets progress be read per module or per object type.patrick_weber11, published 2025-08-15

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

Since updated for cds up, which is the shortest answer the core now offers, and the post carries that update inline rather than leaving the original standing.published 2025-02-13
Clean Core maturity and the new Extensibility LevelsClean Core maturity and the new Extensibility LevelsSets out SAP's Clean Core Level concept, the successor to the 3-Tier Development Model, which grades extensibility by how upgrade-safe it is rather than by where it runs: Level A covers on-stack extensions on released RAP and CDS views plus side-by-side apps on BTP, Level B covers upgrade-stable classic APIs listed in the Cloudification Repository, Level C covers internal-object use flagged through SAP's Changelog for SAP Objects, and Level D covers direct modifications and implicit enhancements that ABAP Test Cockpit checks must block. Choosing between an on-stack and a side-by-side implementation is left to the SAP Application Extension Methodology, and the official Level classifications are filed under SAP Note 3578329.EmilianoAyub, published 2025-12-19
Clean Core清洁核心概况介绍Clean Core清洁核心概况介绍Explains Clean Core as SAP's architecture methodology for decoupling custom code from standard code, and walks through the A-D grading SAP uses for a single extension's cleanliness: D for direct modification of standard tables, programs, classes or functions, or disallowed patterns such as implicit enhancements; C for internally developed functions calling unreleased APIs; B for using only SAP's classic or released APIs (BAPI, ALV Grid, BAdI); A for side-by-side extensions reached only through released interfaces onto the SAP Build extension suite. It lays out a six-step roadmap for reaching Clean Core — inventorying existing extensions, setting a reduction target, surveying SAP's extension routes (SAP GUI SE80, Fiori custom fields and logic, BTP high/low-code, workflow/RPA), writing a decision tree, splitting new development from legacy migration, and reviewing periodically — while noting that in-app development is not inherently unclean and that real decisions should weigh ROI rather than follow the theory absolutely.ArthurYang, published 2025-11-10
Enhancing Standard BAPIs: When and How to Do ItEnhancing Standard BAPIs: When and How to Do ItWalks through why a standard BAPI needs enhancing — a missing field, an extra validation, logic before or after the call, or a performance tweak — and five ways ABAP offers to do it: a BAdI found in SE18/SE19, an append structure for extra fields, a classic user exit wired through SMOD/CMOD, a wrapper function module copied from the original, or an implicit enhancement when no other extension point exists. Each technique gets its own steps, and two carry a short ABAP code example.Shantalinga, published 2025-09-29
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. The piece walks a worked example — a Fiori app that triggers the Purchase Requisition API — through CDS, RAP, OData activation on SAP Gateway, and authorization via business catalogues, and frames the whitelist of released APIs and CDS views as upgrade-safety rather than a restriction.ArthurYang, published 2025-11-24
SAP Job Scheduling Service: Set Job Run Status with the REST API and Node.jsSAP Job Scheduling Service: Set Job Run Status with the REST API and Node.jsWalks through recovering a stuck asynchronous job run in SAP Job Scheduling service: when a triggered app fails to call back, the run stays at ACK_RECEIVED and eventually UNKNOWN, since the scheduler never assumes success or failure on its own. The fix is a Node.js script that reads a downloaded service key, gets an OAuth2 client-credentials token, and calls PUT /scheduler/jobs/{jobId}/schedules/{scheduleId}/runs/{runId} with a success/message body to set the run to FAILURE or SUCCESS by hand.DenisDuev, published 2025-08-11
SAP S/4HANA Cloud: Scheduling Background Jobs Using Application Job TemplatesSAP S/4HANA Cloud: Scheduling Background Jobs Using Application Job TemplatesWalks through moving S/4HANA Cloud and ABAP Environment job scheduling off ECC's SUBMIT and JOB_OPEN/JOB_SUBMIT/JOB_CLOSE pattern onto the Application Job Framework: a job template built from an ABAP class that implements IF_APJ_DT_EXEC_OBJECT and IF_APJ_RT_EXEC_OBJECT, then scheduled through the Manage Application Job Templates Fiori app or programmatically with CL_APJ_RT_JOB_SCHEDULING_API's SCHEDULE_JOB method. The resulting job is tracked in the Monitor Application Jobs app, where status, logs and failed runs are reviewed.TalluriSudheerKumar, published 2025-08-06
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
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
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

CAP multitenancy with Work ZoneCAP multitenancy with Work ZoneA gap in the tooling and the manual edit that closes it. cds add portal wires the Portal service, which is deprecated; Work Zone supports multitenancy but has no equivalent command.

Developing CAP java/node.js mixed mono Multitenant SaaS Applications with Shared DatabaseDeveloping CAP java/node.js mixed mono Multitenant SaaS Applications with Shared DatabaseTwo CAP projects, one Java and one Node.js, in one npm workspace sharing a single tenant database.

Guide to Process Automation APIs - Part I - Getting StartedGuide to Process Automation APIs - Part I - Getting StartedExplains how to call SAP Build Process Automation's REST and OData APIs directly: OAuth2 client credentials with a service key runs as the service, while a user token (OAuth2JWTBearer) runs as the calling person, which matters wherever an API records who acted — approving a task, or reading instances from a shared environment. Since the Public environment is deprecated as of the end of 2025, a call into any other environment also needs an environmentId query parameter.Dan_Wroblewski, published 2025-07-14

Processes start from events, APIs, schedules or forms, the forms built in SAP Build Process Automation, as UI5 applications or in SAP Build Apps; they reach other systems through the SAP Connectivity service with actions over APIs from sources that include CAP and RAP OData destinations and SAP Business Accelerator Hub specifications, and users reach them through SAP Build Work Zone and SAP Mobile Start, with SAP Task Center as the place tasks are managed. Decisions, Process Visibility, Processes and Automations come inside the one subscription and cannot be decoupled from it; CAP appears only as a source of API actions, and the examples are business scenarios such as mass job requisitions in SAP SuccessFactors.published 2025-05-14

Workflow development using SAP Cloud Application Programming Model and SAP Build Process AutomationWorkflow development using SAP Cloud Application Programming Model and SAP Build Process AutomationAn argument about where logic belongs rather than a wiring guide. The author's case is that pulling mapping, preprocessing and JavaScript into the process model makes it unreadable to the process owner who has to maintain it, so the model should stay thin and CAP should hold the domain model, the authorisation annotations, the events and the API consumption. Each of those is then shown in turn against SBPA — including publishing CAP events into process visibility.Venugopal, published 2025-02-18
