User exit for LP12

[former_member414371]

Hello,

I'm working with transaction LP12 now and I'm trying to debug the user exit I have implemented.

Please correct and help if I'm wrong with the fallow:

The user exit used is MWMPP001 (EXIT_SAPLLCPP_001 => ZXLPPU01.

I have created a project and I have activated this user exit.

I do the follow steps:

1) Start the transaction LP12 and input the Plant and Supply area:

2) Mark the items and click WM Material Staging (in debug mode):

I expect to find the call of user form.

I think I do something wrong, because I put a break point in the user exit form and the debugger doesn't stop on this breakpoint.

And my question is When the user form is called? How to find her?

Please help.

Thanks!
