Update Invoice Distribution DFF value to posted invoice

Hi

As our organization needed to capture additional information under the invoice distribution, we enabled DFF at invoice distribution. Now we need to update previous invoice distribution like with DFF value for reporting.

When tried to update it gives the message "The invoice is selected for payment so it cannot be adjusted,accounted or deleted"

Is there a way to enter the DFF value either manual/upload to the posted or accounted invoices.

Appreciate if anyone could assist in this. Thanks in advance.

Regards

NM
