  Cause:
  The error message CNV_20100647 usually occurs during a data migration or conversion process when the system identifies that certain rows in a table do not meet the required criteria for the migration or conversion. This could be due to various reasons, such as:

  Solution:
  To resolve this issue, you can take the following steps:

  Correct Data Issues: Once you identify the problematic rows, you may need to clean or transform the data to meet the required criteria. This could involve:
  
  Updating incorrect values.
  Removing duplicates.
  Filling in missing information.
  Ensuring that the data adheres to the expected formats and constraints.
