Defining default values in ME51N as per PR document type
I have a question regarding Purchase requisition default values field behavior. At our client there are 200 users who will be raising varying kinds of PR like Asset PRs, Service PRs & Material PRs. I was wondering if there is any way to default values in ME51N as per document type. e.g if a user select document type for creating asset PR ..account assignment category field should be defaulted by A along with other fields like Plant , requisition which i know can be defaulted by standard ..I want to vary behavior of account assignment category,item category , material group field with respect to document types. Since i am not MM guy so apologies in advance if my question seems illogical in any way.
