PO report showing PO line item with and without account assignment

Hi Gurus,

Is there any standard SAP report through which I can get PO report showing PO line item with and without account assignment. For example, if PO is created against Sales Order (a/c assignment cat "E") of WBS (a/c *** cat "Q") or with account assignment, it should show all type of PO line items in single. I tried with ME2L, Me2N, ME80FN and search in many forums but could not find any such report.

thanks
