We are using 8.1D version. I tried on the new item it seems to works fine.

But on the existing item, all others location are active but one is "on Demand" and I tried to change it to "Active" it would not save the changes. And when I go to "Edit Location" the "Edit Item" listing showed "YES" even it is on demand. Normally, when an item is "On Demand" it should not be a "YES". If I remove it from the listing then Only it allows me to save the changes.

Thanks.
