CAP: Unit Testing using Mocha and ChaiCAP: Unit Testing using Mocha and ChaiUnit tests added to an existing CAP service rather than written alongside a new one, which is the harder and more common case. Mocha and Chai wired up by hand, from a time before cds.test was the obvious answer.jhodel18, published 2020-05-31

Enhancing Unit Testing in SAP CAP Java Applications with GitHub CopilotEnhancing Unit Testing in SAP CAP Java Applications with GitHub CopilotBuilt on SAP's own CAP Java unit-testing guide, and the question is narrow: how much of that does an assistant actually write for you.

Draft handlingSAP only
A simple example of a SAP RAP Application based on Legacy API without UUID keysA simple example of a SAP RAP Application based on Legacy API without UUID keysWalks through building a managed RAP business object over the Flight Reference Scenario's Travel and Booking entities with unmanaged save and late numbering, so CRUD operations route through the legacy /DMO/FLIGHT_TRAVEL_CREATE, _UPDATE and _DELETE function modules instead of generated persistence, a worked case of ABAP's transactional model. Covers the ADJUST_NUMBERS and SAVE_MODIFIED saver methods that map preliminary draft keys to the legacy-assigned travel and booking IDs, and a GetDefaultsForBookings action that proposes the next booking ID during draft handling.cseijas, published 2025-09-01

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

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
