Create a Search to Show 'From' and 'To' location on Inventory Transfer in Separate Co

I came across an "Answer" in Netsuite's SuiteAnswers that boggles the mind a bit, although it seems to work.

The topic "Create a Search to Show 'From' and 'To' location on Inventory Transfer in Separate Columns" (Answer ID 14355) tells you how to search for From and To locations on an inventory transfer.
