I am having complaints about the QC backlog report being real slow - I tried to run and it is taking a long time to generate - Have there been any changes that are causing this report to crawl  
 
also, when it does finally finish there are alot of part #'s with nothing in QC - see below:

I have 4 pages of part #'s and the only one that is valid is the second one listed here - all the other parts show nothing in QC like the two others above.  
 
Anyone have any idea what might be causing this?
