Another kind of Ghost Part and how to delete from ASM

I had another engineer come to me with "cannot upload to Windchill because of 123xyz.prt not unique error. Part 123xyz.prt is not in the ASM and has not been since several revisions ago."

I tried the usual reference viewer and break/delete old unused dependencies. There was plenty to fix there but the 123xyz.prt was not listed. Still blocked from upload. 

Model info got me this info on the culprit

"SUBSTITUTION IS BY SIMPLIFIED REPRESENTATION
COMPONENT IS NOT ACTIVE IN ANY SIMPLIFIED REPRESENTATION"

After googling for a while the solution is to convert the old feature to display it in the ASM model tree

So have to add config.pro

cnvt_unused_subst_comps_on_retr yes

Then the part shows in the ASM model tree again as suppressed and can be deleted.

Ghost Part beaten once more.

Is specific to family table fixes but is applicable here.
