Fiori Elements Analytical Table with CAP: Does it work with V2 and V4?Fiori Elements Analytical Table with CAP: Does it work with V2 and V4?A question in the title and an answer in the post, with the boundary drawn carefully: this is an analytical table inside a List Report, not the Analytical List Page, and the two protocol versions do not behave the same.published 2023-04-03

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

Computed field example in CAPComputed field example in CAPAn answer to a Community question — how to count the entities on the far side of an association — written up as a short post rather than left in a thread. The answer combines CDS with Node.js service events, which is the seam worth noticing: some of what looks like modelling is expressed in the model and some has to be computed when the request arrives, and the boundary between them is not obvious from either side.published 2019-08-21

Connect SAP CAP (Node.js) to On-Premise/Private PostgreSQL using SAP Cloud ConnectorConnect SAP CAP (Node.js) to On-Premise/Private PostgreSQL using SAP Cloud ConnectorAn end-to-end route from a CAP Node.js application on Cloud Foundry to a PostgreSQL database that is never made publicly reachable, over BTP Connectivity and the Cloud Connector using a TCP destination and SOCKS5. The part worth having is that it covers the deployer as well as the server: the generated PostgreSQL deployer has to reach the same private database to deploy the CDS model, and a guide that only connects the runtime leaves you with a schema you cannot install.Kalaikovan, published 2026-08-07

Creating a Hybrid CAP (Node.js) Profile with PostgreSQL on BTP from Business Application StudioCreating a Hybrid CAP (Node.js) Profile with PostgreSQL on BTP from Business Application StudioHybrid testing is documented for HANA; this is the same profile against a PostgreSQL instance on BTP, driven from a BAS dev space rather than a laptop.
