Hi, 

We have had a number of invoices created in the last couple of months with the incorrect due date, this was due to the reduced number of days in Feb skewing the system calculation which has now been fixed.

Would it be possible to do a mass change of due dates of invoices in question.

I have ran a debug whilst testing the due date amendment and found as expected that this can only be done when the Invoice is in ‘Preliminary’ status.  Most/if not all of the invoices are in ‘PostedAuth’ status.

I am thinking that we could possibly achieve this using RMB > Customer Instalment Plan and Discounts

ABSTRACT_PAYMENT_PLAN_API.MODIFY__

Would this work?
