• What is the cause and solution for SAP error message CNV_MBT_CWB025 - No conversion logic found for table &1 ?

  The SAP error message CNV_MBT_CWB025 indicates that there is no conversion logic found for a specific table during a data migration or conversion process. This error typically arises in the context of using the SAP S/4HANA Migration Cockpit or other data migration tools, particularly when dealing with custom or non-standard tables.
  Cause:
  
  
  Missing Conversion Logic: The primary cause of this error is that the system does not have any defined conversion logic for the specified table (&1). This can happen if:
  
  The table is custom and does not have a predefined mapping in the migration tool.
  The migration project is not fully configured to handle the specific table.
  The necessary transformation rules or logic have not been implemented.
  
  
  
  Incorrect Configuration: The migration settings may not be correctly configured to include the table in question.
  
  
  Version Compatibility: If you are using an older version of the migration tool or if there are compatibility issues with the source and target systems, this error may occur.
  
  
  Solution:
  
  
  Define Conversion Logic: 
  
  If the table is custom, you will need to create a conversion logic for it. This involves defining how the data from the source table should be transformed and mapped to the target table in the SAP system.
  You can do this by using the appropriate transaction codes or tools provided by SAP for data migration (e.g., LSMW, SAP Data Services).
  
  
  
  Check Migration Settings: 
  
  Review the migration project settings to ensure that the table is included in the migration scope.
  Ensure that all necessary configurations are in place for the migration tool to recognize and process the table.
  
  
  
  Consult Documentation: 
  
  Refer to the SAP documentation for the specific migration tool you are using. This may provide insights into how to define conversion logic and troubleshoot related issues.
