PO Creation/Change User Exit/Badi (Screen)

Hi experts,

I have got a requirement to change the PO creation/change screen to activate the Net Price (NETPR) in the line item section.

When Creating /Changing POs with Consignment line items (item category = K )Net price column is inactive ( in default ). Could you please let me know any suggestions to activate this column for enter data.

I'm not an expert in MM so may be this is kind of a contradiction.

Anyway please give me some ideas.

Thanks,

Chaminda
