MB_MIGO_BADI

I am implementing MB_MIGO_BADI and calling a screen with an additional field not standard to migo.

When the posting was successfull I save the field to the mseg table. When debugging is activated (only a breakpoint), my code gets run and everything works fine. But when I delete the breakpoint, it doesn't work. I've tried commit work and to write to the it_mseg table. The commit work does not work and the it_mseg table is somehow locked to changes.

Can someone pleaaaase help.
