  The SAP error message CNV_10020302 indicates that intervals have already been created for the specified object (denoted by &1 and &2). This error typically arises during data migration or conversion processes, particularly when using SAP's data migration tools.
  Cause:
  The error occurs when the system detects that there are already existing intervals for the specified object. This can happen in scenarios such as:
  
  Attempting to create new intervals for a data object that has already been processed.
  Running a migration or conversion program that tries to create intervals without checking if they already exist.
  A previous migration process was interrupted or not completed, leaving behind existing intervals.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Intervals: 
  
  Use transaction codes like SE16 or SE11 to check the relevant tables for existing intervals. The specific table will depend on the context of the migration (e.g., CNV_10020_INTERVALS or similar).
  Identify the intervals that have already been created for the specified object.
  
  
  
  Delete or Adjust Intervals:
  
  If the existing intervals are no longer needed, you can delete them. Be cautious and ensure that you are not deleting necessary data.
  If the intervals need to be adjusted, you can modify them as required.
  
  
  
  Review Migration Process:
  
  Ensure that the migration process is being executed correctly. Review the steps and parameters being used to avoid creating duplicates.
  If the migration was interrupted, consider restarting it from a safe point, ensuring that it does not attempt to recreate existing intervals.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration tool you are using. There may be specific guidelines or known issues related to this error.
