  The SAP error message CNV_10020675 typically relates to issues encountered during data conversion processes, particularly when using the SAP Data Migration tools or during system migrations. This specific error indicates that there is a problem with the length of a field (FValObj) in the conversion process.
  Cause:
  The error message can be broken down as follows:
  
  Converter path &1: This indicates the specific path in the conversion process where the error occurred.
  Conversion rule &2: This refers to the specific rule that is being applied during the conversion.
  &3: This part usually provides additional context or details about the error.
  Length of FValObj is only &4: This indicates that the length of the field (FValObj) is shorter than expected, which is causing the conversion to fail.
  
  The root cause of this error can be:
  
  Data Mismatch: The source data does not conform to the expected format or length defined in the conversion rules.
  Configuration Issues: The conversion rules may not be correctly configured to handle the data being processed.
  Data Quality Issues: The data being migrated may contain unexpected or invalid values that do not meet the length requirements.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Conversion Rules: Review the conversion rules defined in the migration tool. Ensure that they are correctly set up to handle the data being processed.
