• What is the cause and solution for SAP error message S#455 - You are not authorized to assign roles to users ?

  The SAP error message S#455, which states "You are not authorized to assign roles to users," typically indicates that the user attempting to assign roles does not have the necessary authorizations to perform this action. This is a common issue in SAP systems where role-based access control is implemented.
  Cause:
  
  Insufficient Authorizations: The user lacks the required authorization objects to assign roles to other users. This could be due to missing roles or authorizations in their user profile.
  Role Restrictions: The roles being assigned may have restrictions that prevent certain users from assigning them.
  Profile Issues: The user’s profile may not include the necessary permissions to manage user roles.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to analyze the authorization check. This will show which authorization object failed.
  Review the user’s roles and authorizations in transaction SU01 (User Maintenance) or PFCG (Role Maintenance).
  
  
  
  Assign Necessary Roles:
  
  If the user needs to assign roles, ensure they have the appropriate role that includes the necessary authorizations (e.g., S_USER_AUTH, S_USER_PRO, S_USER_AGR).
  You may need to work with your SAP security team to grant the required authorizations.
  
  
  
  Role Management:
  
  If the roles being assigned have specific restrictions, review the role definitions in PFCG to ensure that the user has the necessary permissions to assign them.
  
  
  
  Consult Security Policies:
  
  Ensure that the user’s actions comply with your organization’s security policies. Sometimes, certain actions are restricted for compliance reasons.
  
  
  
  Testing:
  
  After making changes to the user’s authorizations, test the role assignment again to confirm that the issue is resolved.
  
  
  
  Related Information:
  
  
  Authorization Objects: Familiarize yourself with the relevant authorization objects that control user role assignments, such as:
  
  S_USER_AUTH: Authorization for user maintenance.
  S_USER_PRO: Authorization for user profile maintenance.
  S_USER_AGR: Authorization for role assignment.
  
  
  
  Transaction Codes:
  
  SU01: User Maintenance
  PFCG: Role Maintenance
  SU53: Authorization Check Analysis
  
  
  
  Documentation: Refer to SAP documentation or your organization’s internal guidelines for managing user roles and authorizations.
  
  
  If the issue persists after checking the above points, it may be necessary to involve your SAP Basis or security team for further investigation.
