• What is the cause and solution for SAP error message CNV_CDMC_CA102 - No domains found in the customer namespace ?

  The SAP error message CNV_CDMC_CA102: No domains found in the customer namespace typically occurs during the data migration process, particularly when using the SAP Customer Data Migration Cockpit (CDMC). This error indicates that the system is unable to find any domains defined in the customer namespace, which are necessary for the migration process.
  Cause:
  
  Missing Domain Definitions: The primary cause of this error is that there are no domain definitions available in the customer namespace. Domains are used to define the permissible values for fields in the data migration process.
  Incorrect Namespace Configuration: The customer namespace may not be correctly configured or may not exist in the system.
  Authorization Issues: There may be authorization issues preventing the system from accessing the necessary domain definitions.
  
  Solution:
  
  
  Check Domain Definitions:
  
  Go to transaction code SE11 (Data Dictionary) and check if any domains are defined in the customer namespace (usually starts with a specific prefix like Z or Y).
  If no domains exist, you will need to create the necessary domains that are required for your migration.
  
  
  
  Create Domains:
  
  If domains are missing, create them using transaction code SE11. Define the domain with the required data type and value range.
  Ensure that the domains are correctly assigned to the relevant fields in your data model.
  
  
  
  Verify Namespace Configuration:
  
  Ensure that the customer namespace is correctly configured in your SAP system. You can check this in transaction SE03 (Transport Organizer Tools) under the "Namespace" section.
  If the namespace is not set up correctly, you may need to consult with your SAP Basis team to configure it properly.
  
  
  
  Check Authorizations:
  
  Ensure that the user executing the migration has the necessary authorizations to access the domains in the customer namespace.
  You may need to check the user roles and authorizations in transaction PFCG.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation related to the Customer Data Migration Cockpit for any specific requirements or configurations that may be necessary for your migration scenario.
