Need RANKX to exclude Blanks

[DivyaReddy]

Dear PBI enthusiasts!

I am relatively new to PowerBI and struggling through this one scenario. Use case - 

1. I have a parameter (type of customer - Domestic / International / Contractors) and depending on what the user chooses, I need to use that as my column. There is a TotalSales calculated DAX which is UnitPrice*Qty. 
2. Super simple:) However I need to show only top 5 AND exclude any blanks. 
3. I got the Top5 using RankX, but not able to exclude blanks - tried many things, so would greatly apprciate your help. I have attached a sample PBXI file. (Hmm...not sure how to insert the test file...)

Thank you in advance!

In the RANKX function, don't use the whole table as the first argument but FILTER it by the cells/entries that don't have BLANKs. That's also simple. And if the cell is BLANK, just don't calculate the rank. Something like:

[Ranking] = 
var AllItemsNonBlank = 
    filter(
        // Due to ALLSELECTED this is a relatve
        // ranking. If you want an absolute ranking,
        // use ALL( T[Item] ) instead.
        allselected( T[Item] ),
        not isblank( [your measure to rank with] )
    )
var Result =
    if( not isblank( [your measure to rank with] ),
        rankx(
            AllItemsNonBlank,
            [your measure to rank with]
        )
    )
return
    Result
