Interfaces for Revenue Accounting Item Classes 
The system generates a separate RFC function module for every revenue accounting item class. With this RFC function module, you transfer revenue accounting items for a class to Revenue Accounting (FI-RA). The naming convention for the function modules is /1RA/xxxx_RAI_CREATE_API, where xxxx stands for the four-character name of the class.
The generated RFC function module is adapted to the structure of the revenue accounting item class with its parameters.
In the standard system, a COMMIT WORK (or ROLLBACK WORK in the case of an error) occurs every time the RFC function module is called. This means that every RFC function module represents a logical unit of work (LUW) as standard. You can override this in the IV_TEST parameter. See the documentation in the system.
If the RFC function module is called, the system writes an application log for the processing of the transferred revenue accounting items. You can display this application log with the transaction SLG1 for the object FARR and the subobject CREATE.
Caution
When you update the profitability analysis and transfer the characteristics for the derivation of the profitability segment COPA_MI01, the structure of the characteristics for profitability analysis (COPACRIT) have to be identical in the Customizing system and target system.
