• What is the cause and solution for SAP error message CNVC_SCWB_ZMESSAGE120 - Check VIEW_AUTHORITY_CHECK and CNV_MBT_AUTHORITY_CHECK for user & ?

  The SAP error message CNVC_SCWB_ZMESSAGE120 typically indicates that there is an issue with user authorization when trying to access certain functionalities or transactions in the SAP system, particularly in the context of data migration or conversion processes. This error is often encountered in the context of SAP S/4HANA migrations or when using the SAP S/4HANA Migration Cockpit.
  Cause:
  The error message suggests that the user does not have the necessary authorizations to perform the action they are attempting. Specifically, it points to two checks:
  
  VIEW_AUTHORITY_CHECK: This check verifies if the user has the necessary authorizations to view certain data or execute specific transactions.
  CNV_MBT_AUTHORITY_CHECK: This check is related to the Migration Object and ensures that the user has the required permissions to access migration-related functionalities.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after encountering the error to see the authorization check failure. This will provide insights into which specific authorization object is missing.
  Review the user’s roles and authorizations in transaction SU01 or PFCG. Ensure that the user has the necessary roles assigned that include the required authorizations for the migration activities.
  
  
  
  Assign Missing Authorizations:
  
  If you identify missing authorizations, you may need to assign the appropriate roles or modify existing roles to include the necessary authorization objects.
  Common authorization objects that may be relevant include:
  
  S_TCODE (Transaction Code)
  S_USER_AUTH (User Authorization)
  S_DATASET (File Access)
  S_MBT_* (Migration-related authorizations)
  
  
  
  
  
  Consult with Security Team:
  
  If you do not have the necessary permissions to modify roles or authorizations, consult with your SAP security team or administrator to ensure that the user is granted the appropriate access.
  
  
  
  Testing:
  
  After making changes to the user’s authorizations, have the user log out and log back in, then attempt the action again to see if the issue is resolved.
  
  
  
  Related Information:
  
  Documentation: Refer to SAP Help documentation for details on authorization objects and roles related to data migration.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to the CNV_MBT or VIEW_AUTHORITY_CHECK.
  Transaction Codes: Familiarize yourself with transaction codes like SU01 (User Maintenance), PFCG (Role Maintenance), and SU53 (Authorization Check) for managing user authorizations.
  
  By following these steps, you should be able to identify and resolve the authorization issues leading to the CNVC_SCWB_ZMESSAGE120 error.
