• What is the cause and solution for SAP error message /SAPPCE/01066 - Final invoice is already posted; No posting of advance payment request ?

  The SAP error message /SAPPCE/01066 Final invoice is already posted; No posting of advance payment request typically occurs in the context of the SAP Project System (PS) or Controlling (CO) modules when there is an attempt to post an advance payment request for a project or service that has already been finalized with a final invoice.
  Cause:
  
  Final Invoice Posted: The primary cause of this error is that a final invoice has already been posted for the project or service. Once a final invoice is posted, it indicates that all billing and financial transactions related to that project or service are complete.
  Advance Payment Request Attempt: The system does not allow for any further advance payment requests to be processed after a final invoice has been issued, as this would conflict with the finalized financial status of the project.
  
  Solution:
  
  Check Invoice Status: Verify the status of the invoices related to the project or service. Ensure that the final invoice is indeed posted and that no further transactions are expected.
  Review Project Financials: If there is a need for additional payments, review the project financials to determine if there are any outstanding costs or adjustments that need to be addressed.
  Consult with Finance Team: If there is a legitimate reason for needing to post an advance payment after a final invoice, consult with your finance or accounting team. They may need to reverse the final invoice or make adjustments in the system.
  Use Correct Transaction: If you are trying to post an advance payment for a different project or service, ensure that you are using the correct transaction code and that the project is eligible for advance payments.
  
  Related Information:
  
  SAP Documentation: Refer to SAP Help documentation for detailed information on billing processes in the Project System and Controlling modules.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FB60 (Enter Incoming Invoice), FBL1N (Vendor Line Item Display), and CJ20N (Project Builder) for managing project-related financial transactions.
  User Roles and Authorizations: Ensure that you have the necessary authorizations to perform the required actions in the system.
  
  If the issue persists after following these steps, it may be beneficial to engage with your SAP support team or consult SAP Notes for any specific patches or updates related to this error message.
