Partner Profit center in Inter Co Billing

Hi All,

I have a question related to Inter Co Scenario..

A. Co Code 1700 supplies to 2200

B. PGI happens and the COGS is posted in 1700

C. Then Inter Co invoice is raised by 1700 on 2200. This records revenue and AR in 1700

D. Based on the C, IDOC is triggered to record COGS and AP in 2200 .. Here, Partner Profit center (PPC) field is Blank for COGS

Note 815972 relates to Step C of my process... However, the "Mirror Image" IDOC that I post in 2200 to record the expense part does not get any PPC

Is there SAP note which can populate the PPC in the FI Doc posted through IDOC in 2200...

I have explored all options and I feel substitution in FI is the only way... Any thoughts?
