• What is the cause and solution for SAP error message CNV10920009 - For table &1 and field &2, no conversion routine was found. ?

  The SAP error message CNV10920009 indicates that during a data conversion process, the system could not find a conversion routine for a specific table and field. This typically occurs in the context of data migration or data transfer processes, such as during system upgrades or when using SAP's Data Migration tools.
  Cause:
  
  Missing Conversion Routine: The primary cause of this error is that there is no defined conversion routine for the specified field in the specified table. Conversion routines are used to transform data from one format to another during migration.
  Incorrect Configuration: The configuration for the data migration might be incorrect or incomplete, leading to the absence of the necessary conversion routines.
  Custom Fields: If the field in question is a custom field or part of a custom table, it may not have a predefined conversion routine in the standard SAP system.
  
  Solution:
  
  
  Define a Conversion Routine:
  
  If you have access to the ABAP development environment, you can create a custom conversion routine for the specific field. This involves writing an ABAP function module that defines how to convert the data for that field.
  Use transaction code SE37 to create a new function module and implement the necessary logic for data conversion.
  
  
  
  Check Existing Routines:
  
  Review the existing conversion routines in the system to see if there is a similar routine that can be reused or modified. You can check the standard SAP routines in transaction SE11 or SE37.
  
  
  
  Update Migration Configuration:
  
  Ensure that the migration configuration is correctly set up to reference the appropriate conversion routines. This may involve updating the mapping or transformation rules in the migration tool you are using.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration tool you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services) for guidance on how to handle conversion routines.
