+When a lot/serial number is selected on an unbuild order, this module
+filters the available source locations to only those where the
+lot/serial number is currently stocked.
+
+If stock exists in a single location, it is automatically set as the
+source location. If stock exists in multiple locations, the list is
+narrowed down for the user to choose from. A warning is displayed if
+no stock is found for the selected lot/serial number.
