• What is the cause and solution for SAP error message CNV_20700210 - No authorization to execute function module &1 in execution system ?

  The SAP error message CNV_20700210 indicates that a user does not have the necessary authorization to execute a specific function module in the execution system. This error typically arises during data migration or conversion processes, particularly when using SAP's tools for data transfer or system conversion.
  Cause:
  The primary cause of this error is a lack of authorization for the user executing the transaction or program that calls the function module. This can happen due to:
  
  Missing Authorization Object: The user may not have the required authorization object associated with the function module.
  Role Assignment: The user’s role may not include the necessary permissions to execute the function module.
  Profile Issues: The user profile may not be correctly configured to allow access to the function module.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to see what authorization checks failed. This will provide insight into which specific authorizations are missing.
  
  
  
  Review Roles and Profiles:
  
  Go to transaction PFCG to review the roles assigned to the user. Ensure that the role includes the necessary authorizations for the function module in question.
  If the role does not include the required authorizations, you may need to modify the role or create a new one that includes the necessary permissions.
  
  
  
  Add Missing Authorizations:
  
  If you identify missing authorization objects, you can add them to the user’s role. Common authorization objects related to function modules include:
  
  S_FUNCTION: Authorization for function modules.
  S_TCODE: Authorization for transaction codes that may call the function module.
  
  
  
  
  
  Consult with Security Team:
  
  If you do not have the necessary permissions to modify roles or profiles, consult with your SAP security team or administrator to request the required authorizations.
  
  
  
  Testing:
  
  After making changes to the user’s roles or authorizations, have the user log out and log back in, then attempt to execute the function module again to verify that the issue is resolved.
  
  
  
  Related Information:
  
  Function Module: A function module is a reusable piece of code in SAP that can be called from various programs or transactions. The specific function module causing the error will be indicated in the error message (represented by &1).
  Authorization Concept in SAP: SAP uses a role-based access control system where users are assigned roles that contain authorizations. Understanding how roles and authorizations work is crucial for troubleshooting authorization issues.

  By following these steps, you should be able to identify and resolve the authorization issue causing the error message CNV_20700210.
