Disable input from PO quantity in ME22N

[Former Member]

I would like to know where can I add the code in user-exit if I want to disable input for PO quantity in ME22N if the final invoice indicator is set.

I've tried on enhancement MM06E005, but dunno which component should I place the code.

I'm new to user-exits, and hope any one can solve my problem, thanks.

Hi,

The field which you need to disable is MEPO1211-MENGE.

You have to create an implementation for your enhancment and write your code there.

Loop at screen.

case screen-name.

when ' MEPO1211-MENGE '.

screen-active = 0.

endcase.

Endloop.

Hi,

You can try putting that code in the enhamcement MM06E005 which you suggested.

Try debugging the transaction and put a break point in your added code inside the enahmcement.

Check if the code you have added is working fine.

For creating enhancements follow this:-

Can you provide me with more guidelines?? since I cannot access to the link you provided.

I just knew I need to put coding in MM06E005, but actually no idea which place inside the program should I add.

Really thanks for your help
