No backend PO in ECC5?

Question

Hi Gurus,
Please can someone shed some light on the following error.
We have activated extended classic scen in srm 5.0, but our srm PO does not replicate over to ECC5 as a display only doc. The checks our basis team have undertaken are:
i. No idocs are visible in WE05
ii. errors are displayed in RZ20 say: (a) IDOC comms error: 'error sending IDoc to FI/CO backend for PO3xxxxxxxx, (b) Comm error checking account assignment for PO3xxxxxxxx in system
iii. the trans type and doc no's are consistent in srm.
iv. no entries in srm table REQREF
Any input would be appreciated
Thank you,
Mikey

Answer 1

Hi Muthu,
Thank you for the hint. I can now sucessfully get an outboubnd IDOC from our SRM system, however, the Inbound IDOC fails in R/3 with the message. Please can you elaborate what function module should be used for message type BBPCO01 as I am using Process Code 'BAPI' in R/3 transaction code WE20.
Thanking you,
M.
Function module not allowed: BAPI_IDOC_INPUT1
Message no. B1252
Diagnosis
The function module BAPI_IDOC_INPUT1 and the application object type which were determined are not valid for this IDoc.
Procedure
1. Please check that the process code in the inbound partner profile is correct.
2. If this is the case, you should check the ALE inbound methods ALE inbound methods for the process code and see whether the specified function module and application object type are correct.
3. If this is also the case, then the function module and the application object type are not permitted for the logical message type, message variant, message function and basis type that are contained in the IDoc control record. You should check whether the correct values have been assigned to these fields in the control record. If they do have the correct values, then the assignment to the function module and the application object type needs to be maintained.
