• What is the cause and solution for SAP error message SWF_CST391 - RFC user is not assigned a required role ?

  The SAP error message SWF_CST391 indicates that an RFC (Remote Function Call) user is not assigned a required role. This typically occurs in the context of workflow or when a background job is trying to execute a function that requires specific authorizations that the user does not have.
  Cause:
  
  Missing Role Assignment: The RFC user does not have the necessary roles assigned in the SAP system. This can happen if the user was created without the appropriate authorizations or if roles were removed or not properly assigned.
  Authorization Issues: The user may lack specific authorizations required to execute the function or access the necessary data.
  Configuration Issues: There may be a misconfiguration in the workflow or the RFC destination settings.
  
  Solution:
  
  
  Check User Roles:
  
  Go to transaction SU01 (User Maintenance) and enter the RFC user ID.
  Check the roles assigned to the user. Ensure that the user has the necessary roles that include the required authorizations for the workflow or function being executed.
  
  
  
  Assign Required Roles:
  
  If the required roles are missing, you can assign them by using transaction PFCG (Role Maintenance).
  Create or modify a role to include the necessary authorizations and assign it to the RFC user.
  
  
  
  Review Authorization Objects:
  
  Identify the specific authorization objects that are required for the workflow or function. This can often be found in the documentation or by consulting with your security team.
  Ensure that the roles assigned to the user include these authorization objects.
  
  
  
  Test the Configuration:
  
  After assigning the necessary roles, test the workflow or function again to ensure that the error is resolved.
  
  
  
  Check Workflow Configuration:
  
  If the issue persists, review the workflow configuration to ensure that it is set up correctly and that the RFC user is intended to execute the workflow.
  
  
  
  Consult SAP Notes:
