• What is the cause and solution for SAP error message TK900 - User &1 has no authorization for the selected function ?

  The SAP error message TK900 indicates that a user does not have the necessary authorization to perform a specific function or access a particular transaction. This is a common issue in SAP systems, where user roles and authorizations are strictly managed to ensure security and compliance.
  Cause:
  
  Missing Authorization Object: The user lacks the required authorization object that is necessary for the transaction or function they are trying to access.
  Role Assignment: The user may not have been assigned the correct role that includes the necessary authorizations.
  Authorization Profile: The authorization profile assigned to the user may not include the required permissions.
  Transaction Restrictions: Certain transactions may have restrictions based on user roles or organizational levels.
  Changes in Authorization: Recent changes in the authorization roles or profiles may have inadvertently removed access.
  
  Solution:
  
  
  Check User Roles:
  
  Go to transaction SU01 (User Maintenance) and enter the user ID.
  Check the roles assigned to the user and ensure that the necessary roles are included.
  
  
  
  Review Authorization Objects:
  
  Use transaction SU53 immediately after the error occurs to see which authorization check failed. This will provide insight into which specific authorization object is missing.
  Alternatively, you can use transaction SUIM (User Information System) to analyze user authorizations and roles.
  
  
  
  Modify Roles:
  
  If the user is missing the required authorization, you may need to modify the role using transaction PFCG (Role Maintenance) to include the necessary authorization objects.
  Ensure that the role is properly assigned to the user after making changes.
  
  
  
  Consult with Security Team:
  
  If you do not have the necessary permissions to make changes, contact your SAP security team or administrator to request the required authorizations.
  
  
  
  Testing:
  
  After making changes, have the user log out and log back in to test if the issue is resolved.
  
  
  
  Related Information:
