You can define a special authorization for every document type. To do this, you need to determine what document types in which form employees are allowed to process.
Authorizations are checked for the following activities:
Posting documents
Document display and line item display
Changing documents
Programs that evaluate documents.
The system does not check the authorization for document types that are not assigned an authorization group.
In Customizing for Financial Accounting , carry out the activity Maintain Authorizations under Financial Accounting Global Settings .
Enter an authorization group in the document type. You then assign authorization for this authorization group to the employees who will work with this document type.
For each document type, you can specify whether users are required to enter a reference number or the document header text.
