Specifically, the error states that the change number you are trying to use is not a valid successor for the specified object (like a material or a document).
  Cause:
  This error typically arises due to one of the following reasons:

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Change Number Sequence:

  Consult Change Management Documentation:
  
  Review the documentation or guidelines for change management in your organization to ensure you are following the correct procedures for using change numbers.
  
  
  
  Use Transaction Codes:
