Yes, it's true that this was changed in Adagio Payables V8.1D because we noticed that Adagio Payables was occasionally not taking discounts that were available (although no one else had ever noticed this). However, as part of fixing this, we also "decided" that we would not select invoices with a Due Date greater than the cheque date. This means that at some sites we are now selecting fewer invoices than are expected (hence my question to the original post).

In my investigation, I never saw more invoices being selected than I expected, only fewer.

At the moment, the only way to get these invoices included in a System Check Run is to mark them "Force", or move the date of the check forward to pick them up (which might have unintended accounting side effects).

We will work on changing this so that only the "Due on or before" and Discount dates affect invoice selection. I'm sorry for the inconvenience this may cause.
