• What is the cause and solution for SAP error message GB158 - No authorization to create substitutions ?

  The SAP error message GB158, which states "No authorization to create substitutions," typically occurs when a user attempts to create a substitution in the SAP system but lacks the necessary authorizations to perform this action. This error is commonly encountered in the context of SAP's workflow and substitution functionalities, where users can delegate their tasks to others.
  Cause:
  The primary cause of this error is insufficient authorization in the user's role or profile. Specifically, the user does not have the required permissions to create or manage substitutions in the SAP system. This can happen due to:
  
  Missing Authorization Objects: The user’s role may not include the necessary authorization objects related to substitution management.
  Role Configuration: The roles assigned to the user may not be configured correctly to allow substitution creation.
  Profile Issues: The user profile may not be updated or may not include the necessary permissions.
  
  Solution:
  To resolve the GB158 error, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after encountering the error to see which authorization check failed. This will provide insight into what specific authorization is missing.
  
  
  
  Review User Roles:

  Modify Roles:

  S_TCODE (Transaction Codes)
  S_USER_AUTH (User Authorizations)
  S_WFAR_OBJ (Workflow Authorization)
