  The SAP error message CD821, which states "The last change document number was allocated," typically occurs when the system has reached the maximum number of change document numbers that can be allocated in a specific number range. This can happen in various modules where change documents are used to track changes to data.
  Cause:
  
  Exhausted Number Range: The number range for change documents has been exhausted. Each change document is assigned a unique number, and once the maximum number is reached, the system cannot allocate a new number.

  Check the current number range intervals and see if the maximum number has been reached.

  Adjust Settings:
  
  If necessary, adjust the settings to allow for automatic number range extension if your business process requires it.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP Basis or functional team for specific instructions on managing number ranges for change documents.
