HCM Payroll: Sending payroll results from HR to FI with different org. structure - RPCIPE00_OLD

[12329]

Hello SAP Community,

We have following situation: 

A company code is sending payroll postings from HR System to FI System. In order to create a posting, the HR system uses RFC communication to read the relevant GL accounts from FI system through symbolic account mapping. The report used on HR side is RPCIPE00_OLD.

Problem: The client has different company code, controlling area and chart of accounts in HR and FI systems. So the simulation check to read the GL accounts from FI is failing, as the query from HR is coming with old org. structure.

SAP Note 3434196 offers a possibility of changing the company code via method GET_SUBSTITUTION_BUKRS but is not applicable for the RPCIPE00_OLD. 

HR system is looking for a solution where all corrections are done in FI system.
How can this problem be solved? Is there any way to modify the RFC communication on FI side, so that the query from HR is replaced with new org. structure values and correct GL accounts are reported back to HR? Or can the modification be done only on HR side?

Thank you very much in advance.
Best regards

Have you used the conversion rules where 

HCM Company code is X while sending the results it will convert as per values in FI system as Y.

and your second question , No Corrections is possible in FI system as the results were already generated in HCM wil only get transferred via IDOC into FI System
