We need to turn on the Multi-Location Inventory and I'm trying to do some testing in the Sandbox.  After reading all the disastrous threads on this feature, I'm trying to do all the testing in the Sandbox that is possible.  Unfortunately, the Simple Inventory Distribution fails.  We have 57,928 items that are showing up to be distributed.  Netsuite support recommended that I clear cache, make sure there's no negative inventory, try it in another browser, etc etc.  The rep also commented that an inventory distribution record can only contain 1,000 items.  I'm assuming that's why it's failing.  Nothing worked and
