• What is the cause and solution for SAP error message CNV_MBT_46373 - Parent table name and child name should not be same ?

  The SAP error message CNV_MBT_46373 indicates that there is a conflict in the naming of a parent table and its child table during a data migration or conversion process. Specifically, this error occurs when the names of a parent table and its corresponding child table are identical, which is not allowed in the context of the data model.
  Cause:
  
  Naming Conflict: The error arises when the system detects that a parent table and its child table have the same name. This can happen due to incorrect configuration or data mapping during the migration process.
  Data Model Design: In a relational database, a parent-child relationship is established where the parent table holds the primary records, and the child table holds related records. Having the same name for both tables can lead to confusion and ambiguity in data handling.
  
  Solution:
  
  Check Table Names: Review the configuration or mapping settings in your data migration project. Ensure that the parent and child tables have distinct names.
  Rename Tables: If you find that the parent and child tables are indeed named the same, you will need to rename one of them to resolve the conflict. This may involve updating the data model or the migration scripts.
  Review Migration Logic: Ensure that the logic used for data migration correctly identifies and differentiates between parent and child tables. This may involve revisiting the migration strategy or the tools being used.
  Consult Documentation: Refer to SAP documentation or guides related to the specific migration tool or process you are using. There may be specific recommendations or best practices for naming conventions.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context on handling table relationships during migration.
  Data Migration Tools: If you are using specific SAP tools for data migration (like SAP S/4HANA Migration Cockpit, SAP Data Services, etc.), consult the documentation for those tools for guidance on handling parent-child relationships.
  Testing: After making changes, conduct thorough testing to ensure that the migration process works as expected without further errors.
  
  By addressing the naming conflict and ensuring that the parent and child tables are distinctly named, you should be able to resolve the CNV_MBT_46373 error.
