The message states that the change number you are trying to use is not a valid predecessor for the specified object.
  Cause:
  This error typically arises due to one of the following reasons:
  
  Invalid Change Number: The change number you are trying to use does not exist or is not valid for the object you are working with.

  Review Object Type: Ensure that the change number is applicable to the object type you are working with. If there is a mismatch, you may need to select a different change number.
  Check Status: Ensure that both the change number and the object are in the correct status to allow for the operation. If necessary, change the status or unlock the object/change number.
