RankX with 2 fields

[Roberto456]

Hello All.

For some reason 1 RankX formula works but the other doesnt.

Below is Dax:

Product Rank (Name) =

VAR CURRENTPRODUCT = MAX('(Dim) Product'[Product_Name])

RETURN

RANKX(FILTER(ALLSELECTED('(Dim) Product'),'(Dim) Product'[Product_Name] = CURRENTPRODUCT),[Master],,DESC,Dense)

Product Rank (Category) =

VAR CURRENTCATEGORY = MAX('(Dim) Product'[Category])

RETURN

RANKX(FILTER(ALLSELECTED('(Dim) Product'),'(Dim) Product'[Category] = CURRENTCATEGORY),[Master],,DESC,Dense)

 For some Reason the Name one works but the Cateogry doesnt, even though they are the both exact same DAX.

Can anyone help me fix this?

Hello @Roberto456 ,

Your formulas are calculated columns, right?

If so, modify them as follows:

Product Rank (Name) = 

RANKX(FILTER(ALLSELECTED('(Dim) Product'),'(Dim) Product'[Product_Name] = EARLIER('(Dim) Product'[Product_Name])),[Master],,DESC,Dense)

Product Rank (Category) = 
RANKX(FILTER(ALLSELECTED('(Dim) Product'),'(Dim) Product'[Category] =EARLIER('(Dim) Product'[Category] )),[Master],,DESC,Dense)

Hello.

I found the solution.

No these are measures, for dynamic ranking.

The problem was, that unless I put in the 2nd field as the most granular part of the product (from the table being referenced) the ranking wouldnt work.

which is why category / product wouldn't work, (product wasnt the most granular field).

I had to duplicate the product table and make sure that product name was the most granular field and then reference that table instead.

I would have preffered to use a VAR table, but I couldnt find a way to RankX from it.

Hi @Roberto456 ，

If so ,modify them as below:

RANKX(FILTER(ALLSELECTED('(Dim) Product'),'(Dim) Product'[Product_Name] = EARLIER('(Dim) Product'[Product_Name])),[Master],,DESC,Dense)

Product Rank (Category) = 
RANKX(FILTER(ALLSELECTED('(Dim) Product'),'(Dim) Product'[Category] =EARLIER('(Dim) Product'[Category] )),[Master],,DESC,Dense)

@Roberto456 , It Seems like you are creating a subcategory rank.  Now rank will change based on context. So I rank a measure on product . If I use the product then it will show correct rank. But If Add Category, then it will show product rank inside the category.

But If add say Product ID then I will see all 1. In such case In need use All(product,prodcut_id) to make sure they work together
