Agent access to your systemsBTPABAPCAPAgent access to your systemsGiving an AI agent access to the business data, configuration or operations of systems you run through an MCP server. [Serving your application over MCP](capability:mcp-servers) exposes your own service contract; system access reaches the systems behind it, and one implementation may do both. Development assistance belongs to [agent access to your code](capability:agent-code-access).Agent guidanceCAPBTPABAPAgent guidancePackaged knowledge you hand a coding agent so it gets a framework right unprompted — skills, rule files, instruction packs. Distinct from agent tooling, which is about building agentic features into your application, and from [agent access to your code](capability:agent-code-access), where the agent reads the real project instead of being handed a file about it.Database administrationBTPDatabase administrationRunning the database a project uses once it exists: watching its health and performance, managing users and their access privileges, and keeping backups that a recovery can rest on. Connecting an application to the database is [database connectors](capability:database-connectors), moving files in and out of tables is [importing and exporting table data](capability:data-import-export), and what the instance costs is [consumption monitoring](capability:consumption-monitoring).Database connectorsCAPBTPABAPDatabase 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).Native SAP HANA artifactsCAPNative SAP HANA artifactsUsing native SAP HANA database objects alongside an application’s generated data model, including objects and database features the modelling layer cannot express. Choosing a database is [database connectors](capability:database-connectors); changing an existing schema is [schema evolution](capability:schema-evolution).

September 15th: What's New on developers.sap.comSeptember 15th: What's New on developers.sap.comThomas Jung walks through a week of changes aimed at agentic consumption of developers.sap.com itself: the hosted MCP server gains a published .well-known/mcp.json manifest, curated tools (search_tutorials, get_tutorial_step with a Markdown format option, search_channels), and a listing in the ORD catalog beside its OData, REST and GraphQL APIs. It also documents the site's existing A2A endpoint for the first time and ships a way to turn a tutorial into an installable, cryptographically signed AI Skill with a generated verification script, both concrete instances of agent tooling; separately, five broken GraphQL example queries were fixed and the full SDL is now served, and new sitemap.md, llms.txt fixes and ORD entries round out the site's own metadata publishing.published 2026-09-15
SAP Developer New, July 3rd 2026SAP Developer New, July 3rd 2026A "Did You Know" segment in this SAP Developer News video walks through schema evolution: CAP's ability to add a new field to an entity, or make a compatible change to an existing one, then redeploy the model with no data loss or manual migration. The rest of the July 2026 episode covers that month's Developer Challenge, a SAP HANA Cloud Q2 release announcement and a UI5 survey call, none explained in substance here.published 2026-07-02
SAP CAP Recent Enhancements the HANA Dev Should Know AboutSAP CAP Recent Enhancements the HANA Dev Should Know AboutThomas Jung walks through CAP features for HANA database developers that landed through late 2021: doc comments in the data model (CDL comments propagated into generated database objects via the package.json cdsc.docs compiler option), and schema evolution reaching general availability in the November 2021 release, using the @cds.persistence.journal annotation and cds.hana.journal settings to generate incremental hdbmigrationtable migration scripts instead of dropping and recreating tables. It also walks through two features outside those two: window functions in view column definitions, added in the December 2021 release, and a beta assert_integrity setting that generates database foreign-key constraints from 1:1 associations and compositions.published 2022-02-15
SAP Tech Bytes: Adding Service Implementation to an SAP HANA ProjectSAP Tech Bytes: Adding Service Implementation to an SAP HANA ProjectThomas Jung converts an existing SAP HANA-only project into a CAP one, exposing its native tables, views and a calculation view as CAP service entities with @cds.persistence.exists so they get full create, update, delete and read operations without being redefined. He adds OData V2 support through an adapter proxy for callers still expecting XSODATA-shaped responses, and separately turns on CAP's OpenAPI generation with its Swagger UI test tool. A second part rebuilds the same service layer with a standalone Node.js module instead of CAP, for cases that need more control than CAP's REST or OData defaults give.published 2021-05-07
New SAP Cloud Application Programming Model Sample for Many-to-Many Relationships and Fiori AnnotationsNew SAP Cloud Application Programming Model Sample for Many-to-Many Relationships and Fiori AnnotationsIntroduces SAP-samples/cloud-cap-hana-swapi, a CAP sample rebuilding the abandoned Star Wars API as a six-entity data model (Films, People, Planets, Species, Starships, Vehicles) chosen for its many-to-many, bi-directional relationships and its use as a Fiori Draft deep-editing test case. The author used CAP's OpenAPI functionality to generate both the Swagger UI test tool and entity diagrams for the data model, alongside the OData services and Fiori preview UI.published 2020-12-21
Adding a Swagger UI to Your SAP Cloud Application Programming Model / Node.js ServiceAdding a Swagger UI to Your SAP Cloud Application Programming Model / Node.js ServiceThe problem stated from the other side of the wire: a CAP and HANA backend consumed by frontend developers with no SAP background, who said in the first meeting that they could not work from what the service offered. A browsable API page is the answer, and this is the post the Swagger UI plugin indexed here exists to serve.published 2020-01-23
