PR creation from SAP CRM using SAP PS and WBS element

Hi Gurus,

When we are creating PR from SAP CRM using SAP PS and assigned to WBS element, the system is creating the PR but taking account assignment category as P instead of Q.

In OPTT - account assignment categories for order, we have defined AcctAssCat projects - Q (Proj. make-to-order).

I am not able to understand from where it is picking P???

Please help.

Regards,

Smart
