• What is the cause and solution for SAP error message CNV_OR_PE_GEN008 - Namespace of object &1 is not allowed ?

  The SAP error message CNV_OR_PE_GEN008 indicates that the namespace of the object you are trying to use is not allowed. This error typically occurs in the context of SAP's data migration tools, particularly when working with the SAP S/4HANA Migration Cockpit or other conversion tools.
  Cause:
  
  Invalid Namespace: The object you are trying to access or manipulate belongs to a namespace that is not permitted for the operation you are performing. In SAP, namespaces are used to categorize objects, and certain namespaces may be restricted for specific operations to maintain system integrity.
  Custom Development: If you are working with custom objects or third-party solutions, they may reside in a namespace that is not recognized or allowed by the migration tool.
  Configuration Issues: There may be configuration settings in your SAP system that restrict access to certain namespaces.
  
  Solution:
  
  Check Object Namespace: Verify the namespace of the object you are trying to use. You can do this by checking the object in the ABAP Workbench (SE80) or using transaction SE11 for database objects.
  Use Allowed Namespaces: If the object is in a restricted namespace, consider using objects from allowed namespaces. You may need to create new objects in a permitted namespace or modify your migration strategy.
  Adjust Configuration: If you have administrative access, check the configuration settings related to namespaces in your SAP system. You may need to adjust these settings to allow access to the required namespace.
  Consult Documentation: Review the SAP documentation related to the migration tool you are using. There may be specific guidelines or restrictions regarding namespaces that you need to follow.
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP Support for assistance. They can provide guidance based on your specific system configuration and the objects involved.
