This error indicates that there is an issue with attempting to reverse a billable item that cannot be reversed due to certain conditions.

  Document Type Restrictions: Certain document types may have restrictions that prevent reversal. Check if the document type associated with the billable item allows for reversals.

  Consult with Finance Team: If the item has been processed in a way that prevents reversal, consult with your finance or accounting team to determine the appropriate course of action, such as issuing a credit note.
  Use Alternative Methods: If reversal is not possible, consider using alternative methods to correct the billing, such as creating a new invoice or credit memo to offset the original item.
  Check for Custom Enhancements: If your organization has implemented custom enhancements, check with your technical team to see if any custom logic is affecting the ability to reverse billable items.
