• What is the cause and solution for SAP error message UD012 - Enter the names of both users ?

  The SAP error message UD012 ("Enter the names of both users") typically occurs in the context of user administration, particularly when you are trying to perform a user comparison or a user-related action that requires specifying both a source user and a target user.
  Cause:
  This error arises when the system expects you to input two user names (for example, when comparing user profiles or roles) but one or both of the required fields are left blank. The system cannot proceed without both user names being provided.
  Solution:
  To resolve the UD012 error, follow these steps:
  
  
  Check Input Fields: Ensure that you have entered both user names in the appropriate fields. If you are using a transaction that requires two users (like SUIM or SU01), make sure both fields are filled.
  
  
  Correct User Names: Verify that the user names you are entering are valid and exist in the system. You can check this by using transaction SU01 to look up the users.
  
  
  Re-enter Information: If you have copied and pasted user names, ensure there are no extra spaces or invalid characters.
  
  
  Consult Documentation: If you are unsure about the specific transaction or process you are using, refer to the SAP documentation or help files for guidance on the required inputs.
  
  
  User Roles and Authorizations: Ensure that you have the necessary authorizations to perform the action you are attempting. Lack of permissions can sometimes lead to misleading error messages.
  
  
  Related Information:
  
  Transaction Codes: The error may occur in transactions like SU01 (User Maintenance), SUIM (User Information System), or others related to user management.
  User Administration: Familiarize yourself with user administration concepts in SAP, including user roles, profiles, and authorizations.
