this is querry process analytics. this data only sending to to grid to show in read only mode 

What happens when you run just that QPA call in the expression rule editor?  Does the data you get back look right?

i guessed why it was not showing data in production, as per analysis this queryprocessanalysis is taking too much time. maybe just because of timeout it is not showing data

What is the page size set to?  What happens if you try a smaller value for that?
