SAP Note that verify if service sheet is created and block PO field changes

67 Views

Hi People,

I am an ABAP programmer and I got a MM requirement that I think you can help me.

Here is whats happening:

-


1 - Buyer create PO with field GR-Based Invoice Verification (WEBRE) flagged. (ME21N).

2 - Then user creates Service Sheet(ML81N)

3 - Because service sheet take a time to be aproved, the buyer changes PO, removing the flag of fields GR-Based Invoice Verification (WEBRE) and GR-Goods Receipt indicator(WEPOS) (ME22N) so he can execute MIRO and F110.

User can't reflag the fields (WEBRE) and (WEPOS). So the service sheet stay on "limbo"

-


What I want, is to know if there is any SAP NOTE that verify and block the change on fields (WEBRE) and (WEPOS). So the user can't remove the flag if already exists a service sheet for the PO.

Tks,
