Currently, with the ability to modify kit components in Inventory Manager on the Kit Components tab, a check is performed to determine if the kit is associated with any open line items. If it is, you get a warning and are not allowed to modify the kit's components.
Would like to see a possibly optional exception to have quotes not be part of the open sales line check.
A scenario would be having kit items on quotes often, and having the kit items update to the current components when transferring to an order is acceptable.
