• What is the cause and solution for SAP error message CNV20551380 - Different lengths; &1 is not equal to &2 (in CNV_20551_TSTRUC) ?

  The SAP error message CNV20551380, which states "Different lengths; &1 is not equal to &2 (in CNV_20551_TSTRUC)," typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there is a mismatch in the expected lengths of fields between the source and target structures.
  Cause:
  
  
  Field Length Mismatch: The most common cause of this error is that the length of a field in the source data does not match the length of the corresponding field in the target structure. For example, if a field in the source data is defined as 10 characters long, but the target structure expects a field of 5 characters, this error will be triggered.
  
  
  Data Type Differences: Sometimes, the data types of the fields may also differ, leading to length discrepancies. For instance, a numeric field in the source might be treated as a character field in the target.
  
  
  Configuration Issues: Incorrect configuration in the data migration settings or mapping can also lead to this error.
  
  
  Solution:
  
  
  Check Field Lengths: Review the field definitions in both the source and target structures. Ensure that the lengths of the fields match. You can do this by checking the data dictionary (SE11) for the relevant tables or structures.
  
  
  Adjust Data Mapping: If you are using a migration tool, check the mapping configuration. Ensure that the fields are correctly mapped and that any transformations applied do not alter the expected lengths.
  
  
  Data Cleansing: If the source data contains values that exceed the expected length in the target structure, you may need to cleanse the data before migration. This could involve truncating values or modifying the data to fit the target structure.
  
  
  Modify Target Structure: If it is appropriate and feasible, consider modifying the target structure to accommodate the source data. This may involve increasing the field length in the target structure.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be additional guidelines or best practices for handling field length issues.
  
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like SE11 (Data Dictionary) to check the definitions of the structures involved.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on data migration issues.
  Migration Cockpit: If you are using the SAP S/4HANA Migration Cockpit, review the migration object definitions and mappings to ensure they are set up correctly.
  
  By following these steps, you should be able to identify the cause of the CNV20551380 error and implement a solution to resolve it.
