Hi,
While creating the PO by using Drag & Drop function in ME21N, the partner function (PI,OA) of the vendor are not appering in P.O. Header except VN funtion. But if we created the P.O. Manually (with same PR) it is appering in P.O. I would like to know is this standard fuctionality of SAP or it has any patch/Note to correct it?
