SAP Incentive Management - Understanding of CSN file & CLI Command to generateSAP Incentive Management - Understanding of CSN file & CLI Command to generateCSN met from the far end: not as CAP's compiled model but as the interchange format a product hands to Analytics Cloud so a story knows the shape of the data. Explains what CSN is, why the format matters here, and the command that produces one.Yogananda, published 2024-11-19
Consume SAP Document Management using @cap-js/sdm pluginConsume SAP Document Management using @cap-js/sdm pluginStoring attachments in a SAP Document Management repository from a CAP application, using the official plugin. The point the post makes about the plugin is that it brings its own UI: a user attaches any number of documents and one Save writes them all to the repository, so the application does not build an upload surface of its own.published 2024-08-26
Extend Upload Set to Fiori Elements and utilize Document Management ServiceExtend Upload Set to Fiori Elements and utilize Document Management ServiceWritten two months before there was an official plugin, and the author has left the record of that in the page: an update dated 2024-04-04 noting the CAP team released @cap-js/attachments, and another dated 2024-05-21 saying they tested it and wrote up the Object Store variant separately. The hand-built version underneath is still the answer when the plugin's storage choices do not fit.published 2024-02-25

Working with the Attachment plugin - Cloud Application ProgrammingWorking with the Attachment plugin - Cloud Application ProgrammingOne instalment of the author's own series working through the CAP plugins one at a time, and it reads as that: what the plugin does, how it does it, and how to put it in a service. Written from the plugin list in capire rather than from a problem, which makes it the plainest introduction here.published 2024-05-18

Sharing SAP HANA Cloud instance to multiple subaccounts and creating HDI containersSharing SAP HANA Cloud instance to multiple subaccounts and creating HDI containersOne HANA Cloud instance, several subaccounts, an HDI container created from each — the arrangement that keeps a landscape from paying for a database per subaccount.

Extend SAP Cloud Application Programming Model(CAP) Validations with the CAPVAL PluginExtend SAP Cloud Application Programming Model(CAP) Validations with the CAPVAL PluginThe complaint first: the built-in annotations are good for data integrity and poor at telling the user what went wrong, and there is no way to reuse a rule. capval, the plugin the post announces, adds @validation.message alongside the standard annotations rather than replacing them, and @validation.handler for a check written as a class. Published in January 2024, before the 1.2.0 line the README now pairs with @sap/cds 8.0.0 and above; the two annotations it shows are the two the README still documents.published 2024-01-09

SAP Cloud Logging Serviceでコンテナメトリクスを監視するSAP Cloud Logging Serviceでコンテナメトリクスを監視するIn Japanese. 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. The procedure is deliberately independent of application logic — bind the instance, add a startup script and a config file — so it works against an application you already have.kyoneo, published 2024-03-26
