Purchase order item - avoid delete

[Former Member]

Hi Expert,

I have to make a control to avoid the deletion of an item of purchase order.

In other word, when the user press the delete button in the item of purchase order, I have to check variable A.

If A = 'X' --> avoid delete item, and pop for info

else.

delete item

endif.

How I can make it ? There's a BADI, or an user exit ?

Tks a lot.

Hello,

Please implement the Badi "ME_PROCESS_PO" in that go to

if_ex_me_process_po_cust~process_item.

Write the code

DATA : re_data TYPE mepoitem.

DATA : mmmfd_preq_no TYPE mmpur_metafield VALUE 003. "Banfnummer

INCLUDE mm_messages_mac. "useful macros for message handling

CALL METHOD im_item->get_data

RECEIVING

re_data = re_data.

IF re_data-lokez ne space.

CALL METHOD im_item->invalidate( ).

mmpur_metafield mmmfd_preq_no.

mmpur_message_forced 'E' 'ME' '083' text-003 'Deletion not allowed' '' ''. ENDIF.

Hello Suresh,

Tks for your reply, You solved my question !

Anyway there's a little problem:

If the user delete the item, my BADI avoid this operation, but after

the user is blocked, I mean that the error message is always present.

There's a way to restore the situation ?

tks a lot,
