• What is the cause and solution for SAP error message FKKSEC451 - Collective invoice already split; adjustment not possible ?

  The SAP error message FKKSEC451 indicates that a collective invoice has already been split, and therefore, an adjustment cannot be made. This typically occurs in the context of contract accounts receivable and payable (FI-CA) when dealing with collective invoices that have been processed in a way that prevents further modifications.
  Cause:
  
  Collective Invoice Already Split: The primary cause of this error is that the collective invoice has already been split into individual invoices. Once this process is completed, the system locks the invoice for further adjustments to maintain data integrity.
  Invoice Processing: The invoice may have been processed in a way that it is no longer eligible for adjustments, such as being posted to accounting or having been cleared.
  Configuration Issues: There may be specific configurations in the system that dictate how collective invoices are handled, which could lead to this error if not set up correctly.
  
  Solution:
  
  Check Invoice Status: Verify the status of the collective invoice. If it has already been split, you will need to work with the individual invoices instead of the collective one.
  Review Document Flow: Look at the document flow to understand how the invoice was processed. This can provide insights into whether it has been cleared or posted.
  Use Individual Invoices: If adjustments are necessary, consider making them on the individual invoices that resulted from the split rather than the collective invoice.
  Consult with SAP Support: If the issue persists or if you believe it is due to a configuration error, consult with your SAP support team or refer to SAP Notes for any known issues or patches related to this error.
  Training and Documentation: Ensure that users are trained on the proper handling of collective invoices to avoid this situation in the future.
