Connect SAP CAP (Node.js) to On-Premise/Private PostgreSQL using SAP Cloud Connector
An end-to-end route from a CAP Node.js application on Cloud Foundry to a PostgreSQLPostgreSQLA relational database. For CAP it is the production database when the answer is not HANA, reached through an adapter that translates CDS queries into its SQL. 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.

Database connectorsCAPBTPDatabase connectorsConnecting an application’s data model and queries to a database, including the differences in supported queries, types and schema management between database implementations. Changing an existing schema belongs to [schema evolution](capability:schema-evolution).DestinationsCAPBTPDestinationsReaching a system that is not yours — an S/4HANA tenant, an on-premise service, a third-party API — without the address, the credentials or the tunnel being written into the application. The destination is the indirection, and the reason an endpoint can move without a redeploy.

Bridging Python and SAP HANA: Inside the sqlalchemy-hana Open-Source DialectBridging Python and SAP HANA: Inside the sqlalchemy-hana Open-Source DialectA Devtoberfest 2026 data-track session (DAT-21) in which one of the maintainers of sqlalchemy-hana, the open-source SQLAlchemy dialect published in SAP's GitHub organisation, opens up what sits between Python and SAP HANA. It walks the five dialect classes that render statements, types, DDL, identifiers and sequences, and the HANA specifics they absorb: the FROM DUMMY a bare SELECT needs, a limit injected when only an offset is given, string compiled to NVARCHAR, and quoted case-sensitive identifiers against Python's lowercase. The rest covers schema migrations with Alembic on HANA's transactional DDL, the recently added async support and vector types, and that HANA Cloud and HANA 2 are supported while HANA 1 is not.SAP Developers, published 2026-09-29
CAP Foundry: Engineering SAP CAP Applications from Business Intent with Guardrailed AICAP Foundry: Engineering SAP CAP Applications from Business Intent with Guardrailed AICAP Foundry is a prototype that generates a CAP Node.js project with SAP Fiori elements from a written business requirement, discovering the actual data shape from a chosen source — SQLite, a configured SAP HANA HDI container, offline EDMX, live OData through the SAP Destination service, or approved SAP BTP ABAP objects — instead of inventing one. The generated application can carry a Fiori draft lifecycle with optimistic concurrency via ETags and annotation-driven Fiori elements list and object screens, localized independently of the underlying service contract. Attachments can be added with upload, download and delete, gated on a malware-scan status, and the generated project still has to compile, build and pass its generated tests before the run is accepted.Shahid, published 2026-08-20
Expose S/4HANA Cloud OData API as an MCP Server via CAP Node.jsExpose S/4HANA Cloud OData API as an MCP Server via CAP Node.jsA step-by-step walkthrough that wraps SAP S/4HANA Cloud's Outbound Delivery OData v2 API in a CAP Node.js service and exposes it through @cap-js/mcp, so an MCP client can list the generated tools, query the delivery entities and call a custom createDelivery action over JSON-RPC. The remote S/4HANA connection is configured two ways in package.json: direct Basic Authentication credentials for local hybrid testing, and a named BTP destination for the app once deployed to Cloud Foundry.Jacky_Liu1, published 2026-07-29
Principal Propagation from BTP Web App to S/4HANA via SAP Integration SuitePrincipal Propagation from BTP Web App to S/4HANA via SAP Integration SuiteWalks through configuring principal propagation from a BTP web app, through SAP Integration Suite and Cloud Connector, to an on-premise S/4HANA system, so the backend receives calls as the logged-in user rather than a shared service account. The BTP Destination service uses OAuth2JWTBearer to exchange the user's Cloud Identity Services JWT for an Integration Suite token, and the iFlow's OData V2 receiver adapter reaches S/4HANA through Cloud Connector with Principal Propagation authentication. The Cloud Connector Subject Pattern builds the outbound certificate's CN from the token's user_name claim, which is populated from the IAS email rather than the sub claim, so identity resolution on S/4HANA hinges on that email matching a resolvable logon name.Joni, published 2026-07-10
Using RFC Function Modules and BAPIs in SAP Build Process AutomationUsing RFC Function Modules and BAPIs in SAP Build Process AutomationWalks through calling an S/4HANA BAPI (BAPI_BILLINGDOC_CREATEMULTIPLE, to create a billing document) from an SAP Build Process Automation action: mapping the virtual host to the internal system in SAP Cloud Connector over the RFC protocol and exposing the needed function modules, then creating an RFC-type destination in the BTP cockpit with the virtual message server and SMLG logon group. Once those two are in place, SAP Build lists the exposed BAPIs and RFCs for use in an action.MrRaj, published 2026-07-09
Creating an SAP SD Billing Document Using a BAPI in SAP Build and Accessing It Through 'Joule Work'Creating an SAP SD Billing Document Using a BAPI in SAP Build and Accessing It Through 'Joule Work'Walks through the two pieces of connectivity a SAP Build Process Automation action needs to call an on-premise BAPI: mapping the virtual host to the internal S/4HANA host in Cloud Connector over the RFC protocol, and creating an RFC-type destination in the BTP cockpit so BAPI_BILLINGDOC_CREATEMULTIPLE becomes a selectable action. The resulting process creates an SD billing document from a sales document number and is reached through SAP Build Work Zone, including from the Joule Work mobile app.MrRaj, published 2026-06-29

Establishing the connection and its destination before the action project exists is RFC connectivity and Destinations done for a low-code consumer rather than a CAP service.

Implementing Dynamic Subaccount-Based Routing in SAP CAP with SAP BTP DestinationsImplementing Dynamic Subaccount-Based Routing in SAP CAP with SAP BTP DestinationsWhy environment variables are the wrong place for backend endpoints in a CAP application, and what replaces them: cockpit destinations resolved at runtime, with the subaccount or instance identified as the request is handled. The argument is about redeployment — an endpoint kept in the environment means a deploy every time it moves — and the shape it produces is one codebase serving several landscapes without a build per landscape.Dnyaneshwar Salve, published 2026-03-18

从BTP Launchpad里的sapui5应用里调用部署的CPI IFLOW从BTP Launchpad里的sapui5应用里调用部署的CPI IFLOWA short follow-up to the author's earlier post on calling a deployed CPI iflow from a standalone-router SAPUI5 app, adjusted for the case where the app runs inside the BTP Launchpad: the fetch call is built from the launchpad component's own base URI, and the app's xs-app.json approuter route maps a /cpi/* path to a destination that fronts the CPI iflow runtime, with XSUAA authentication on the route. It also walks the MTA build and cf deploy commands used to push the app, scaffolded with generator-easy-ui5, to BTP.Jacky_Liu1, published 2023-06-13

SAP BTP Destinations in a Nutshell Part 1 - Motivation & NoAuthentication DestinationsSAP BTP Destinations in a Nutshell Part 1 - Motivation & NoAuthentication DestinationsOpens a series on SAP BTP Destinations by walking through the simplest case, a NoAuthentication destination from one CAP Node.js app to another on Cloud Foundry, shown two ways: executeHttpRequest from @sap-cloud-sdk/http-client, and a manual sequence that reads the destination service's credentials from VCAP_SERVICES, fetches an OAuth token, and requests the destination by name before calling its URL. The manual path is written deliberately verbose to show what the Cloud SDK call does behind the scenes; later parts of the series cover the other destination types.JakobFra, published 2023-05-23
