I am trying to change the Warehouse Location view from Physical Locations to Virtual Locations, but when I try to save changes I'm getting a "Can not find production location" error.  I've tried setting up a new warehouse, make other changes to the existing warehouse, etc. and I get the same error when I try to save.  We are moving from Enterprise to Community and we have our locations setup the same as in Enterprise, and we are not getting the error message in Enterprise. We are using version 13.
