Wanted to post this as a reminder to users of QBI:
You select to invoice, and receive error message similar to one of the following:
PartPickList: ID not found:
ClientPickList: ID not found:
RatePickList: ID not found:
QBI only obtains QuickBooks and AyaNova information when QBI first loads - so if you enter new information into either QuickBooks or AyaNova (such as new clients, or new rates or new parts) with QBI already running - QBI will not be aware of it until you exit out of QBI and refresh the QuickBooks and AyaNova connection from the main Plugins menu.
If you encounter an issue, do check out solutions to other common issues/messages at http://www.ayanova.com/qbi7webHelp/common_issues__messages.htm
