CaRD Posting — interface for S/4HANA

CaRD Posting makes the business logic of your S/4 system callable from outside: function modules, BAPIs and ABAP classes including their methods can be addressed from your own programs, from portals, from web applications or from a third-party system. What goes in and comes back is JSON — the format everything outside the SAP world works with anyway.

Generic instead of bespoke every time

The decisive difference to a conventionally developed service: the interface is generic. The call itself states which module or class is to be executed with which parameters — no separate service has to be developed, transported and documented for each new function. New requirements become a question of configuration rather than development.

Controlled, not open

Generic does not mean open: your authorisation concept defines who may call which modules and classes at all. Custom authorisation objects can be defined for this, so external access reaches exactly as far as you permit — and every call stays traceable.

Typical use cases

• Bring data from outside into S/4 and have it posted through the regular logic
• Fetch data out of S/4 without rebuilding a copy of the logic
• Real-time processing instead of nightly batch runs
• Use existing business logic, including non-RFC-enabled components
• Connect web applications, portals, shops and third-party systems

Besides the JSON access the interface is also available as a JAR library or as an external reference in a Visual Studio (.NET) project. Available for Windows, Linux, Unix and Java; usable system-wide for all objects and processes. We are happy to advise on the design and implementation of your integration.
