Receivables 9.0A (090511)

Maintenance/Mark Customers Inactive offers only one option to find inactive customers with the field "Last Activity Date". Using last activity date Sept 1/08 this list produces about 60 customers for us. Using Inquiry/Customers and searching with Last Invoice Date or Last Payment Date less than Sept 1/08 AND Start Date less than Sept 1/08 the list produces 818 customers. This is a more accurate inactive list.

I have no idea where AR is coming up with the Last Activity Date. It often has no association with invoices/payments or credits. We have hundreds of customers on our system with no activity what-so-ever for more than a year, but have current activity dates. Many of them are Aug 17, 2009. That is probably the day that we updated to the new AR and our data was converted.

Is there a fix for this or do I have to resort to making each customer Inactive one at a time using Customer Maintenance?
