Need Help with Rankx

I have a problem and can't seem to find whats going wrong!

 

I am using Rankx() function to rank the rows in the resultset table.

 

The RankX function gives two distinct ranks to the rows viz. 1 and the highest rownumber (eg. 20,000) 

 

Here is what my formula looks like:

 

Rank = RANKX (all(TableName),[All_Assets])  --- gives rank = 1 to  rows with All_assets > 0 and  rank =maxRank (something like   20,000)  to rows with All_assets = 0 

 

 I also tried: Rank = RANKX(all(TableName),calculate([All_Assets])) -- gives me the same result. And anyway I don't think I need to include Calculate since " All_assets" is a  measure which is precalculated.

 

All_Assets is a measure which is calculated as follows:

 

All_Assets = DISTINCTCOUNT(TableName[AssetName])

 

 

Any idea, what is going on?

    I think we need some more context around this, can you provide example/sample data? Is there some group/category column you are using that you are ranking? Here is a RANKX problem that I solved yesterday:

     

    Measure = 
VAR __currentCategory = MAX(CategoryRanks[Category])
VAR __tmpTable = ALL(CategoryRanks)
VAR __tmpTable1 = SUMMARIZE(__tmpTable,CategoryRanks[Category],"__Count",COUNT(CategoryRanks[Category]))
VAR __tmpTable2 = ADDCOLUMNS(__tmpTable1,"__Rank",RANKX(__tmpTable1,[__Count],,,Skip))
RETURN MAXX(FILTER(__tmpTable2,[Category]=__currentCategory),[__Rank])

      Thanks!

       

      Here are the pictures of resultsets. I have masked some columns for confidentiality reasons. 

       

      I am giving here an example of rank based on column called "Unmonitored Assets".

       

      Here is how Unmonitored Assets (a measure) is calculated:

       

      Unmonitored Assets = CALCULATE(DISTINCTCOUNT(TableName [AssetName]), TableName [Excepted_Assets] = 0) + 0 --> filtering on column Excepted_assets = 0 and  getting the distinct count for those assets.

       

      The rank measure is as follows: 

      Rank = RANKX (all(TableName),[Unmonitored Assets])  -- > I want to rank the table based on number of "Unmonitored Assets".

       

      Here is what I see: 

       

      Rank = 1 for all Unmonitored Assets >0 

      Rank = 160001 for all Unmonitored Assets =0 

       

      What is going on, anyone?

        Need a sense of your source data. In that table, do [AssetName]'s appear once or multiple times? I really think that you need to do a SUMMARIZE of your table based on some grouping of which I am not clear about yet and then do an ADDCOLUMNS to add a rank column as shown in previous reply.
