Hi Nick,
Glad to hear that's all that was.
Just so you know, there are default settings in the Order Entry company profile for how long to keep completed orders, invoices and credit notes in the 'Current' screens and not purge. This is on the 4th screen - System Defaults. You can set different number of days for each (ie 30 days for orders and 180 days for invoices, etc). These settings are used when running Day End Processing, and can be over-ridden as necessary, including not purging any transactions at all.
