Wonder could someone help me. I have a straight table with several dimensions and few expressions that shows me if stock has been out since yesterday. 1st expression show me the stock balance as of yesterday and the 2nd expression shows me the stock balance from today. 3rd one is simple calculation between the two. So if stock yesterday >0 and stock today =0 it states "Stock out" if not it shows "N/A". Is there a way that i can filter out all N/A values in my table?
