As i want to restrict user to see only relevant PO's for Company codes which he is responsible when he run ME28.
Well before this i have tried various user exits M06E0004 & M06E0005 and ME*...
and search BADI but i didn't found the solution as most of then is triggering after displaying the result..
As i want to restrict the display of irrelevant POs which are not under his company code..
Thanks in Advance.
