This typically occurs in the context of the SAP Contract Accounts Receivable and Payable (FI-CA) module, where preliminary invoices are used to manage billing processes.
  Cause:
  
  Invoice Creation: The error arises when an invoice has already been created based on a preliminary invoice, and the system does not allow the reversal of the preliminary invoice because it has been referenced by a subsequent invoice.
  Status of Preliminary Invoice: The preliminary invoice may have a status that prevents it from being reversed, such as being in a finalized state or having been posted to accounting.
  Business Logic: The business rules configured in the system may dictate that once an invoice is created from a preliminary invoice, the preliminary invoice cannot be reversed to maintain data integrity.
  
  Solution:
  
  Check Invoice Dependencies: Review the invoices related to the preliminary invoice. If an invoice has been created based on the preliminary invoice, you may need to reverse or adjust that invoice first before attempting to reverse the preliminary invoice.
  Use Alternative Methods: If reversing the preliminary invoice is not possible, consider using alternative methods such as creating a credit memo or adjusting the invoice to correct any errors.
  Consult Documentation: Refer to SAP documentation or your organization's internal guidelines for handling preliminary invoices and their reversals.
