In Windchill QS 10.1, in the Fault Tree module, there is a dialog box that you can call up by clicking "Link Data" in the basic event of the fault tree. There used to be the ability to add a second column to the dialog box but I am told that is no longer possible.
Please consider adding this feature to future versions of Windchill QS. This is valuable for two (2) reasons. One, I can uniquely identify which part number I want to link to in a fault tree to a FMEA mode number. Secondly, my component list can have the "Name" field stay generic instead of my being force to make the "Name" field unique for purposes of "Link Data" identification (only one column identifier available). As an example the Name field might have for unique identification "Resistor, smt, R9" in the Link Data column but the Library List uses the generic name "Resistor, smt" and with it a unique prediction data will be lost.
