Probelm in addition of line item in ME21N

Hi,

I am working on a requirement where after providing the data for line item 1 of a PO (ME21N), when the User presses enter, based on certain conditions a new line item should get added to the PO.

Using the BADI ME_PROCESS_PO_CUST and Method Process_ITEM but are not able to get the same.

Any pointers on this will be helpful.

Best regards

Saurabh
