  The SAP error message LAW2_MESSAGES457 indicates that a user does not have the necessary authorization to execute the transaction USMM (which is used for License Administration Workbench). This transaction is typically used for managing and analyzing SAP licenses.
  Cause:
  The error occurs because the user attempting to access the transaction does not have the required authorization object assigned to their user profile. The authorization object typically involved in this case is S_USER_AUTH, which controls access to various transactions and functions within SAP.
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs. This transaction will show you the last authorization check and can help identify which specific authorization is missing.
  
  
  
  Review Authorization Roles:
  
  Check the roles assigned to the user in transaction SU01 (User Maintenance). Ensure that the user has a role that includes the necessary authorizations for transaction USMM.
  
  
  
  Assign Required Authorizations:
  
  If the user does not have the required authorizations, you will need to either:
  
  Modify an existing role to include the necessary authorizations for USMM.
  Create a new role that includes the required authorizations and assign it to the user.
  
  
  
  
  
  Authorization Object:
  
  Ensure that the authorization object S_USER_AUTH is included in the role with the appropriate activity (e.g., 03 for display, 02 for change).
  
  
  
  Transport Changes:
  
  If changes are made to roles or authorizations, ensure that they are transported to the relevant systems if you are working in a landscape with multiple environments (e.g., Development, Quality Assurance, Production).
  
  
  
  Consult with Security Team:
  
  If you do not have the necessary permissions to make changes to user roles or authorizations, consult with your SAP security team or administrator to assist in resolving the issue.
