To freeze inventory items in Physical Count without getting users out of the system: Write a VI Import to IM_Physical. Add the Warehouse Code, Item Number and as the Counted Quantity, set it to a blank column in your spreadsheet. That will ""FREEZE"" just the items in your list. It actually puts in a Count Quantity of zero; so be sure someone does not Update the Register by accident. Then later, come back and update the spreadsheet with counts and set the Counted Quantity Column to your count column. Not sure if this will work with Lot/Serial Valuation, but it works well with Fifo, Lifo, Ave & Standard Cost Items.
