Hello Team,
We have a DB table with following fields, that have Parent-Child hierarchy.
Our reporting requirement is to come up with following tabular visualization, to display only parent Id Categories (C1,C2,C3) with count of child_id’s associated to my Parent. Something as follows:
So, when I select Id -1, the measure should provide the count of child_id’s for it, which is 2 in this case.
I’m SQL guy and very new to DAX, this can be done using a self-join for Id to ParentId in SQL.
Can anyone please provide a DAX expression for the same?
Thanks,
Sundeep

hi @Anonymous
Try this method
First a calculated column
PATH = PATHITEM ( PATH ( TableName[Id], TableName[ParentId] ), 1, INTEGER )Now this MEASURE
No. of Children = VAR myvalue = SELECTEDVALUE ( TableName[Id] ) VAR mycategory = SELECTEDVALUE ( TableName[Category] ) RETURN CALCULATE ( COUNT ( TableName[PATH] ), TableName[PATH] = myvalue, TableName[Category] <> mycategory, ALL ( TableName ) )
