Dear arpit,

Will reward points to u anyways.

Can u also tell me in detail how to use this transaction for MM01.COZ WHEN I DOUBLE CLICK ON MM01 AND GO IN,when I click on fields in fields selection group,multiple values come,and suppose if i want only material type mandatory,then along with material type other fields will also become mandatory.

How to go about this then?

In the screen for MM01 tcode where you put the fields ,change that field properties (when you double click on that field in layout editor you will properties window ) in the Program tab check Input field ( and write code for that field in PAI logic if you want to pass some message to the user when this field is initial ).



Please reward points if helpful..
