• What is the cause and solution for SAP error message CNV_DMC_MM001 - Authority to change is missing ?

  The SAP error message CNV_DMC_MM001 ("Authority to change is missing") typically occurs in the context of data migration or conversion processes, particularly when using the SAP Data Migration Cockpit (DMC) or similar tools. This error indicates that the user does not have the necessary authorizations to perform a specific action or change within the system.
  Cause:
  
  Insufficient Authorizations: The user executing the transaction or process does not have the required authorizations assigned in their user profile. This could be due to missing roles or specific authorization objects that are not included in the user's profile.
  Role Configuration: The roles assigned to the user may not include the necessary permissions for the data migration activities.
  System Configuration: There may be restrictions or configurations in the system that limit the ability to make changes to certain data or settings.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after encountering the error to analyze the authorization check. This will show which authorization object failed and why.
  Review the user's roles and authorizations in transaction SU01 (User Maintenance) or PFCG (Role Maintenance).
  
  
  
  Assign Necessary Roles:
  
  If the user lacks the required roles, work with your SAP security team to assign the appropriate roles that include the necessary authorizations for data migration tasks.
  Common roles that may be required include those related to data migration, data maintenance, or specific modules (e.g., MM for Materials Management).
  
  
  
  Review Authorization Objects:
  
  Identify the specific authorization objects that are missing and ensure they are included in the user's roles. Common authorization objects related to data changes include:
  
  M_MATE_MAR (Material Master)
  M_MATE_DATA (Material Data)
  M_MATE_AUTH (Material Authorization)
  
  
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the Data Migration Cockpit for any specific requirements or configurations that may be necessary.
  
  
  
  Testing:
  
  After making changes to the user's authorizations, have the user log out and back in, then attempt the operation again to see if the issue is resolved.
