hierarchy with measures??!!

[Anonymous]

Assume that we need to create a hierarchy that has Category, subcategory, and product, based on the data model below: 

we all know that creating hierarchy is possible with adding a calculated column with RELATED() function to the table with the lowest granularity, here the Product table: 

                           - To the Product table, add a column that uses ProductSubcategory =                             RELATED(ProductSubcategory[ProductSubcategoryName])

                          - To the Product table, add a column that uses ProductCategory = RELATED(ProductCategory[Product Category Name])

My question is :

will it work with creating measures as well? like below: 

                          - To the Product table, add a calculated measure that uses ProductSubcategory =                             RELATED(ProductSubcategory[ProductSubcategoryName])

                         - To the Product table, add a calculated measure that uses ProductCategory = RELATED(ProductCategory[Product Category Name])

Hi elahemeydani,

The RELATED function needs a row context; therefore, it can only be used in calculated column expression, where the current row context is unambiguous, or as a nested function in an expression that uses a table scanning function. A table scanning function, such as SUMX, gets the value of the current row value and then scans another table for instances of that value. 

So to use RELATED() in measures, you must nest it in a table scanning function.
