SAP Cloud Platform Backend service: Tutorial [12]: CDS : local: buildSAP Cloud Platform Backend service: Tutorial [12]: CDS : local: buildCompiling a CDS model locally with the cds command-line tool, installed from @sap/cds via SAP's own npm registry, before uploading it to SAP Cloud Platform Backend service: cds compile converts the model to CSN by default, --to edmx or --to edm produces the OData V2 or V4 metadata document, and --to hana or --to sql produces the database-specific definition files. It shows the local build catching an error the CDS editor's own validation misses — an entity with no key, valid CSN but invalid OData — before the same model reaches the server's compiler.CarlosRoggan, published 2019-04-15
SAP Cloud Application Programming Model: Deep Insert (4) Consume Remote ServiceSAP Cloud Application Programming Model: Deep Insert (4) Consume Remote ServiceFourth in a long series on deep insert, and the one where the target stops being local. Twenty thousand characters, project files linked, and the earlier parts on UUIDs and multi-level structures are prerequisites the author names.CarlosRoggan, published 2019-07-24

SAP Cloud Application Programming Model: Deep Insert (5) Consume Remote Service with SAP Cloud SDKSAP Cloud Application Programming Model: Deep Insert (5) Consume Remote Service with SAP Cloud SDKThe same thing again through SAP Cloud SDK, published as a deliberate comparison with the part before it — the author says outright that it does what the previous post did, differently. Reading both is how you see what the SDK is actually doing for you.CarlosRoggan, published 2019-07-26

SAP Cloud Platform Backend service: Tutorial [11]: CDS : magic: key: generationSAP Cloud Platform Backend service: Tutorial [11]: CDS : magic: key: generationExplains CDS's UUID key type: giving a key property UUID gets its value generated automatically instead of a hand-picked unused number, as data modelling lets an element's type do, at the cost of a 36-character value unfit for a user-facing display. It then works out how that generated value is addressed in a single-entity read URL — bare brackets in OData V4 against the guid'...' literal V2 requires — citing the OData specification for the difference.CarlosRoggan, published 2019-03-15
