F-04 Post with clearing - Document Splitting issue

Hi Guru,

In the system I have implemented the document splitting by Profit Centre and Segment.

I'm trying to post an Incoming Payment (Tcode F-04) with clearing related to two customer.

During the invoices I inserted two different Profit Centre by customer invoice.

When I post, in one document, the incoming payment related to the two invoices I don't insert the Profit Centre values manually, but I link the payment to the customer invoices to be cleared.

The system is not able to derive the Profit Centre inserted in the customer invoice in the incoming payment posting! I cannot post it neither manually because, rightly, I can insert the Profit Centre only for the Bank accounts and not for the Customer account.

How can I derive the Profit Centre from the customer invoices?

Let me know.

Thanks

Ciao
