• What is the cause and solution for SAP error message CNV_LTHCM_G_10122 - For cluster table &1, RELID &2 is excluded from transfer ?

  The SAP error message CNV_LTHCM_G_10122 indicates that a specific cluster table (denoted by &1) and a specific relationship ID (denoted by &2) are excluded from the data transfer process during a data migration or conversion scenario. This error typically arises in the context of the SAP Landscape Transformation (SLT) or during data migration projects, particularly when using tools like the SAP Data Services or SAP S/4HANA Migration Cockpit.
  Cause:
  
  
  Exclusion Criteria: The cluster table and relationship ID may be excluded from the transfer due to predefined criteria in the migration settings. This could be due to:
  
  Configuration settings that specify which tables or data should be excluded.
  Data integrity or consistency checks that prevent certain data from being transferred.
  The relationship ID may not be relevant or necessary for the target system.
  
  
  
  Data Model Changes: If the target system has a different data model or structure, certain cluster tables may not be applicable or supported.
  
  
  Technical Restrictions: There may be technical restrictions or limitations in the migration tools being used, which prevent the transfer of certain types of data.
  
  
  Solution:
  
  
  Review Migration Settings: Check the migration or conversion settings to see if the cluster table and relationship ID are explicitly excluded. You may need to adjust these settings to include the necessary data.
  
  
  Consult Documentation: Refer to the SAP documentation related to the specific migration tool you are using. This may provide insights into why certain tables are excluded and how to handle them.
  
  
  Data Mapping: Ensure that the data mapping between the source and target systems is correctly defined. If the cluster table is necessary for the target system, you may need to create a mapping for it.
  
  
  Custom Logic: If the exclusion is intentional due to business logic, consider implementing custom logic to handle the data differently or to transform it into a format that is acceptable for the target system.
  
  
  Contact SAP Support: If you are unable to resolve the issue through configuration changes or documentation, consider reaching out to SAP Support for assistance. They may provide specific guidance based on your system configuration and the context of the error.
  
  
  Related Information:
  
  Cluster Tables: These are special types of database tables in SAP that store data in a compressed format. They are often used for storing data that is logically related but may not be frequently accessed.
  Data Migration Tools: Familiarize yourself with the tools available for data migration in SAP, such as SAP Data Services, SAP S/4HANA Migration Cockpit, and SAP Landscape Transformation (SLT).
  Error Logs: Check the error logs or detailed migration logs for additional context or related errors that may provide more information about the exclusion.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to address it.
