How to sum a data table in Power BI

Question

I have a visualization in my report made by data table that pulls entirely from a single table.  

The contents of this table contains several calculated columns which are written in DAX.  One among these columns takes the sum of the previous 3 columns and then returns a value based on a SWITCH statement.  

I am trying to attempt 'SUM'  of the values in this SWITCH statement column in order  to get the total at the bottom. Earlier used the following measure to calculate the SUM

Cyclestar Pay Real Values =
IF(COUNTROWS(VALUES(ClassSchedule[ID of Class]))=1,
[CycleStar Pay],
SUMX(VALUES(ClassSchedule[ID of Class]), [CycleStar Pay]))

I am not able to figure out how to sum the values in this column correctly.

Answer 1

It's a good practice if you avoid the measures that are designed keeping specific visualization in mind. 

Let us consider an example based on the data provided above.

1. The years are identifiers for the rows in the table

2. If any other column or row is added like month then the behavior of the measure will be different

The part of your formula for the calculation the total measure would work  well on the detail rows when iterating over VALUES(Table[Year] instead of Table itself:

MyMeasure3 = SUMX(FILTER(VALUES(Table[Year]),[Amount]>1000),[Amount]-1000)

However, VALUES(Table[Year]) would contain only one row while the filtered table is empty when [Amount]<=1000. 

This means that rows for years with [Amount] lower than 1000 should have a blank value. In case you want to have 0 instead of blank, you can just add 0 to the result:

MyMeasure3 = SUMX(FILTER(VALUES(Table[Year]),[Amount]>1000),[Amount]-1000) + 0

Hope this helps!!
