Aside from the issue of having to be in single user.
It would be benificial to be able to delete multiple inventory items at once. To be able to open an inventory and select multiple items that have zero quantities at one time. Over the years there are many items that are not used anymore and having to delete one item at a time is not time efficient. We already do a back up before we start, and have to be in single user (so outside of working hours) If we could delete multiple at a time, it would save time.
