In attempting to import a physical inventory file we had two items that did not have bin locations.  When trying to Update Actual Inventory using PI-G (ISTS Enhancement date 5/27/15) the program just hung.  No error messages, it just sat there.  Running the old version of the program, we received the message that two items did not have valid bin locations.  After correcting the tags, we were still unable to update actual inventory using the new version of the program.
