Blocking a material type in Transaction MM01
Adding an authorization group on a material type can prevent users from accessing that material type, says SAP security expert Corwin Slack.
In Transaction MM01, I want to block the material type "Non-Stock Material (ie)NLAG." What are the ways to do it?
You can add an authorization group to the material type. An authorization can be added to the material type via transaction OMS2. Users who do not have authorization for M_MATE_MAR for the authorization group on that material type will not be able to maintain it in MM01.
