How To Fix CNV_10020191 - Conv. path &1: Total of fragm. lngths &2 differs from lngth of TDetObj &3

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 191

• Message text: Conv. path &1: Total of fragm. lngths &2 differs from lngth of TDetObj &3

What causes this issue?

The length of the target determination object of converter path &V1& is
&V3&. The total length of the fragments defined by the conversion rules
is &V2&, which means that it is different from the length of the target
determation object. This is not possible.

How to fix this error?

Define the conversion rules so that the following condition is
fulfilled:
Total length of the conversion rules = length of the target
determination object

• What is the cause and solution for SAP error message CNV_10020191 - Conv. path &1: Total of fragm. lngths &2 differs from lngth of TDetObj &3 ?

  The SAP error message CNV_10020191 typically occurs during data conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates a mismatch between the total lengths of fragmented data and the expected length of the target data object.
  Cause:
  The error message can be caused by several factors, including:
  
  Data Fragmentation: The data being processed is fragmented into multiple parts, and the total length of these fragments does not match the expected length of the target data object.
  Incorrect Mapping: There may be an issue with how the source data is mapped to the target structure, leading to discrepancies in length.
  Data Corruption: The source data might be corrupted or improperly formatted, causing the length calculations to be incorrect.
  Configuration Issues: There may be configuration issues in the migration settings that lead to incorrect assumptions about data lengths.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Fragmentation: Review the fragmented data to ensure that the total length of all fragments matches the expected length of the target data object. You may need to adjust the fragmentation logic or the data itself.
  
  
  Verify Mapping: Ensure that the mapping between the source and target structures is correct. Check the data types and lengths defined in the mapping configuration.
  
  
  Data Validation: Validate the source data for any inconsistencies or corruption. You may need to clean or transform the data before attempting the migration again.
  
  
  Review Migration Settings: Check the configuration settings in the migration tool to ensure they are set up correctly. Look for any parameters that might affect data length calculations.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be additional guidelines or troubleshooting steps provided.
  
  
  Logs and Traces: Review the logs and traces generated during the migration process for more detailed error messages or warnings that could provide further insights into the issue.
  
  
  SAP Support: If the issue persists, consider reaching out to SAP Support for assistance. They may have additional tools or insights to help diagnose and resolve the problem.
