In SW 2009, how can I rename the column header for QTY. in a bill of material for an assembly with multiple configurations. I have an assembly with two configurations, one showing the default position and a second with an alternate position. The part numbers, quantities, etc. are identical for each configuration. Should be very simple but so far I can't find the solution. If I rename the header to "QTY.", the name reverts back to "Default/QTY." after I do a rebuild. Very frustrating!
