How to Use NPM Modules Like crypto-js in SAPUI5 Using UI5 Tooling ModulesHow to Use NPM Modules Like crypto-js in SAPUI5 Using UI5 Tooling ModulesWalks through adding ui5-tooling-modules to a SAPUI5 project on UI5 Tooling v3: installing the npm package crypto-js alongside it, then wiring a ui5-tooling-modules-task builder task and a ui5-tooling-modules-middleware dev-server middleware into ui5.yaml so the UI5 module loader can resolve it. A controller then loads crypto-js/sha256 through sap.ui.define and calls it like any other AMD dependency, with the stated limit that the pattern works only inside a controller or other AMD-style module, not through a top-level import or require().DakshKumarSingh, published 2025-09-04
Multi-Origin Service Testing and Troubleshooting in SAP GatewayMulti-Origin Service Testing and Troubleshooting in SAP GatewayWalks through testing a multi-origin OData service in SAP Gateway by passing the $system parameter against a System Alias defined in /IWFND/MAINT_SERVICE, verified with the SAP Gateway Client (/IWFND/GW_CLIENT) and from outside the system with a browser or Postman. Covers three recurring failures — an ignored $system, a 500 from an unconfigured RFC destination or inactive backend service, and a 403 from a missing backend authorization — and how to confirm which alias and backend a request actually hit with /IWFND/TRACES.Ravikumar_H1, published 2025-08-19
DevOps with SAP BTPDevOps with SAP BTPHow SAP frames a delivery pipeline for applications on BTP Cloud Foundry: continuous integration through the SAP Continuous Integration and Delivery service and its pipeline templates for CAP and Fiori, transport and change management across environments, and a section on reasonable alternatives for teams with existing CI infrastructure. Culture first, tools second, and explicit that the setup differs on other BTP environments.published 2025-06-06
Debugging in ABAP Development Tool (Part 1)Debugging in ABAP Development Tool (Part 1)A walkthrough of the ABAP Debugger inside ABAP Development Tools: setting a toggle (hard) breakpoint versus a soft breakpoint that only fires once a session is already active, running up to four debugging sessions on the same program, reading the call stack, and debugging an update function module. It also covers watchpoints with their recent and current values, conditional and user-specific breakpoints, activating and deleting breakpoints, and adding variables such as SY-INDEX to the variables tab.M_Sumaiya_Khatoon, published 2025-09-02

A CODE block's connection-management mode uses a '#' syntax to list, select and show the active SAP HANA connection, drawn from the HANA Database Explorer's saved connections or the project's own Cloud Foundry connection, so any valid SQL statement can then run against the project's HDI container.published 2025-01-01

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

Deploying a CAP app with Fiori app standalone (HTML5 Repo Host)Deploying a CAP app with Fiori app standalone (HTML5 Repo Host)A step-by-step alternative to deploying a CAP app's Fiori frontend through SAP Workzone or Launchpad: exposing it to the SAP HTML5 Application Repository service for SAP BTP instead of serving it straight from @sap/approuter, for zero-downtime content updates, versioning and permissions. It builds a sample with @sap/cds-dk's cds add hana,html5-repo,approuter,mta and cds add xsuaa --for production, generates the Fiori app through Business Application Studio's module wizard, then wires the app router's xs-app.json routes, the mta.yaml service binding and SAP Authorization and Trust Management service before building with mbt and deploying to SAP BTP, Cloud Foundry Runtime.Christopher_Ketzler, published 2025-04-22
First Java Cap ApplicationFirst Java Cap ApplicationA step-by-step walkthrough of a first CAP Java project: com.sap.cds:cds-services-archetype scaffolds the initial Maven project, and the domain model is then rewritten in the db folder with entities, the cuid and managed aspects, associations, compositions and a CodeList, so a hand-coded event handler serving a single entity gives way to a service that CAP's generic persistence handling serves without custom code. It deploys that model to SQLite for local development — cds deploy --to sqlite, then a Spring profile pointing at the generated database file — and ends by adding an index.cds so the model and service can be published as a reusable npm module.bruce_wang3, published 2020-12-08

Building Secure SAPUI5 Applications: Best Practices for DevelopersBuilding Secure SAPUI5 Applications: Best Practices for DevelopersA developer-facing rundown of secure coding habits for SAPUI5 apps: typed bindings and custom formatters to reject bad input before it reaches a handler, encodeHTML() instead of rendering untrusted HTML, keeping tokens and URLs out of local and session storage, and CSRF token handling on the ODataModel. It sets up linting with ESLint and an eslint-config-ui5 rule set to catch unsafe DOM access, eval calls and unused imports as part of CI, alongside the same input validation instinct: reject invalid input early rather than trust the backend to catch it.Manisha_19, published 2025-12-10

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.

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
How to Approve/Reject Task via API in SAP Build Process AutomationHow to Approve/Reject Task via API in SAP Build Process AutomationWalks through the Workflow API's /task-instances PATCH call that SAP Build Process Automation exposes to approve or reject a user task from outside its Inbox, matching the instance ID from the Monitoring tab and the identifier of the button the approval form defines. Covers the permission split between an authenticated user, who needs the ProcessAutomationAdmin or ProcessAutomationParticipant role collection to appear as the one who completed the task, and Client Credentials, which completes it as a generic client identity, plus the error codes the API returns for a missing instance, an already-completed task or an invalid status.Dan_Wroblewski, published 2025-02-10
SAP Build Process Automationで「グループ宛て承認ワークフロー」を構築するSAP Build Process Automationで「グループ宛て承認ワークフロー」を構築するWalks through building a group-addressed approval workflow in SAP Build Process Automation: a user group created in SAP Cloud Identity Services is bound to the app so an approval step can send one request to every group member's inbox at once, closing as soon as any one of them acts. The approval form shown in that inbox carries a Claim button that hides a claimed task from the other members, and the workflow's approval step binds its group recipients to the field the requester chose on the start form.takayuki_tanaka, published 2025-07-25
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

Extending SAP Sales and Service Cloud V2 Using CAPExtending SAP Sales and Service Cloud V2 Using CAPAn extension target that does not run on BTP at all — Sales and Service Cloud V2 sits directly on hyperscalers — so the separation between core and extension is enforced rather than encouraged. That constraint is what makes the post worth reading.Quablab, published 2025-07-09

UI5ers Buzz #56: New full-stack UI5 sample app featuring CAP + OData V4 + draft modeUI5ers Buzz #56: New full-stack UI5 sample app featuring CAP + OData V4 + draft modeA sample app published as code rather than described — SAPUI5 over a CAP service with OData V4 and draft mode — and the note that it was built on what the team learned from an application written in March 2020 to help the German Foreign Office repatriate citizens. That provenance is unusual and worth keeping.AndreasKunz, published 2020-11-06
