MultitenancySAP only
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. The author runs the portal command anyway and then rewrites the resource and module config in mta.yaml to point at Work Zone. Short, and honest that it is a workaround rather than a supported path.published 2025-03-14
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. The interesting part is which sidecar wins: both sub-projects get an MTX sidecar, both have cds.xt.SaasProvisioningService switched off, and a third onboarding project keeps provisioning to itself. Configuration listings rather than prose, and it assumes you already know why you would want this.xuelong, published 2025-01-08

Multitenant SaaS applications on SAP BTP using CAP? Tried-and-True!Multitenant SaaS applications on SAP BTP using CAP? Tried-and-True!The opening post of the Cloud Foundry series, and the one that states the shape of the whole thing: a sample built out of a partner co-innovation project with BCG, then delivered in three graded versions — Basic, Advanced, Expert Features — against a fictional partner's requirements. Read it for the motivation and the map; the implementation is in the three that follow.martinfrick, published 2022-10-19

Tried-and-True! – The Advanced VersionWhat the basic version leaves out and production needs: central user management, and reaching an on-premise S/4HANA from a subscribed tenant.

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

Getting started with cds.ql in NodeJS for CAP - 101 on how to query dataGetting started with cds.ql in NodeJS for CAP - 101 on how to query dataWalks through cds.ql, the query API @sap/cds gives a Node.js CAP service's custom handlers, with worked SELECT, UPDATE, DELETE and INSERT examples against a sample schema — filters, AND/OR conditions, column projections, ordering, limiting, grouping and joining two entities through a schema view. An added correction notes that cds.tx(req) is no longer needed to run a query in newer CAP versions, contradicting the post's own original guidance.published 2022-06-21
