The interface is based on the transactional Remote Function Call (tRFC). This is a simplified technique which enables communication to take place on a program-to-program basis.

In contrast to the sRFC (synchronous remote function call), tRFC buffers the data before it is sent. The application and communication side are thus separate from each other.

The sRFC can, however, be used, in particular, for data acquisition purposes in a mobile data entry environment, i.e. for read accesses.

SAP offers a sophisticated monitoring system for logical error analysis. In the event of an error, messages can be sent to different persons or employee groups from whose inboxes repostings can be made.
