My requirement is to restrict certain users from creating , changing and displaying materials in MM01, MM02, MM03 respectively
based on the material type field with value 'ZABC'.
We have standard SAP authorization object for the field M_MATE_MAR for the material type field. But how to use that for only the value 'ZABC' is not clear. Do I need to include that in my code or will BASIS people will assign this object directly to this value? And please suggest how to use this authorization object for MM01,MM02,MM03.
