Hi,
For Bank accounts, the profit center should usually be defaulted using FAGL3KEH, and let the system post clearing entries for the profit center on the expense side.
However, if you still want to derive the profit center on an intercompany posting.
make sure the intercompany clearing account gets the profit center from the expense lines. and then the bank account item category derives the profit center from intercompany clearing account
