I have a little problem. I have declared a mandatory field (without obligatory).
However, then the multiple selection does not work without having already inserted a material.
My code looks like this right now:
at selection-screen on s_matnr.
if s_matnr is initial.
MESSAGE 'The material number must be filled' type 'E'.
Is there any way to work around this so that the multiple selection works when no material is filled?
