Profit center substitution in delivery from Purchase Order

Hi all

Hi have a stock transfer process between two company (1 sending company and the different target companies). I must change the profit center of sending company following the target company code (profit center A for target company A, B for B,etc.). The sales order substitution for PC doesn't work in this case because the delivery born from a PO not from a SO. I find I can make the change for the goods movement with the exit EXIT_SAPLPCRW_002, but I don't found exit for the delivery document (important for the intercompany invoice profit center). Someone have ideas?

thank
