How to select the vendor from the source list in the PO(me21n) screen ??

Hi

How to select the vendor from the source list in the PO(me21n) screen.

Is there any Sources of Supply tab in the PO just like we have in the PR.

I don't want a PO raised from a PR which has got the Vendor assigned to it already.

Or the SAP doesnot provide the option of Source list/Assign source/Sources of Supply .....in the PO.

Kindly reply
