• What is the cause and solution for SAP error message KEO420 - Function not possible due to lack of authorization ?

  The SAP error message KEO420, which states "Function not possible due to lack of authorization," typically indicates that the user attempting to perform a certain action does not have the necessary permissions or authorizations to execute that function within the SAP system. This can occur in various modules, including Controlling (CO) or Financial Accounting (FI), depending on the context in which the error arises.
  Cause:
  
  Missing Authorization Roles: The user may not have been assigned the appropriate roles that grant access to the required transaction or function.
  Authorization Objects: Specific authorization objects related to the function may not be satisfied. This could include restrictions on company codes, cost centers, or other organizational units.
  Profile Issues: The user’s profile may not include the necessary authorizations due to misconfiguration or changes in the authorization concept.
  Transaction Restrictions: Certain transactions may be restricted based on user roles or profiles, leading to this error.
  
  Solution:
  
  Check User Roles: Verify that the user has the correct roles assigned. This can be done by checking the user’s profile in transaction SU01 (User Maintenance).
  Review Authorization Objects: Use transaction SU53 (Authorization Check) immediately after the error occurs to see which authorization objects are missing. This will provide insight into what specific permissions are lacking.
  Consult with Security Team: If you do not have the necessary access to modify roles or authorizations, contact your SAP security or basis team. They can review and adjust the user’s roles and authorizations as needed.
  Transaction Codes: Ensure that the user has access to the specific transaction codes related to the function they are trying to execute.
  Testing: After adjustments are made, have the user log out and back in to ensure that the changes take effect, and then test the function again.
