Hi,
I know that once a field is made mandatory in SPRO, its SAP standard behavior to show Data missing for a particular field as a message upon Saving for any particular SAP object.
We have a particular requirement in PM Notification creation (IW21) screen, such that once user clicks on Save button a pop-up message to appear showing all mandatory fields that need to be filled, rather than a standard message that appear one after another upon filling mandatory fields.
Purpose is that user to know on start what mandatory fields need to be filled even in different Tabs. This is because mandatory fields in Tab not Active are not taken into consideration upon Saving.
Regards
Faisal
