Every time once you log into QBI, QBI will run a pre-flight check to obtain a cache of QuickBooks data, AyaNova data, to see if you have configured your preferences, and will compare existing linked QuickBooks objects with AyaNova objects.
QBI will prompt each unlinked or missing QuickBooks object one by one, identifying the item "item name" is missing or set to Inactive in QuickBooks and confirming if you want to remove the link. QBI will prompt yes no cancel.
If you select yes the item will be unlinked.
If you select no QBI will go on to the next mismatch in the list if any.
If you select Cancel QBI will abort the startup and shut down itself.
Do note that if you delete or set to inactive something in QuickBooks after you have already successfully logged into QBI, as QBI will already have its populated cache of QuickBooks items - QBI will not know that you have since deleted or set to inactive. QBI caches the QuickBooks database only at startup because retrieving individual items on the fly from the QuickBooks database would be painfully slow.
