Idoc process code for message type FIPAYM

I'm trying to replicate DME (generated from FI-TV) from HCM to ERP by program RFFOALE1.

Added message type FIPAYM to distrib.model. autogenerating partner profile (tr BD82) didnt create mapping with process code.

in tr WE20 tried to add process code FI04, BAPI for input parameter of mess.type FIPAYM. but they are not applicable.

so which process code can unpack Idoc FIPAYM and create DME from Idoc?
