Profit-Center derivation in case of intra-company with external P/O

Hello,

I work within ECC 6.0 with new G/L and profit center accounting.

I wonder about the system behaviour in the following case:

1. profit center (PC) #1 is doing a sales order and needs material from PC#

2. PC #2 generates a purchase order (naming PC#1 in the P/O)

3. goods receipt leads to the posting

debit stock (PC#2) credit GR/IR (PC#2) ...o.K. from my side

4. invoice receipt

debit GR/IR (PC#1) credit A/P (PC#1)

5. subsequent postings (costs on sales orders) o.K.

As you can see debit and credit an the GR/IR are not balanced on profit center level.

Does anyone have an idea how to solve that? Is there a user exit or something?

Thanks and best wishes for 2012
