## Calculate row data from two different tables using the filter

I have two tables. I need to get difference of Sum from filtered rows of two tables.

In the example below I need to sum up all incomes by department. I can easily do that by creating matrix table which displays Sum of total income by department.

What I want is the summary table below where each row in the column 'Difference' witll add up total incomes from table "Real Income' by department and subtract EstIncome value from 'Est' table for the same department.

I can create measure for each department using CALCULATE(SUM('Real Income'[Income), 'Real Income'[DEPTID]="101A") and subtract the value from another table for same department but that will create column for each department.

 Real Income Est Income dept Income dept EstIncome 101A 10000 101A 16000 102A 20000 102A 21000 101A 15000 Summary dept Difference 101A 9000 102A -1000

This will be come significantly easier if you create a "lookup table" that holds all the departments.

Then it is simply:

Total Est  := SUM('Estimates'[EstIncoming])

Total Real := SUM('Real'[Incoming])

Delta := [Total Real] - [Total Est]

When creating your summary table, you would place Departments out of the new lookup table on rows (which would cause both fact tables to be filtered, via the magic of the relationships you create).

One way to create the lookup table, is to use the "Calculate Table" on the modeling ribbon:

Departments = DISTINCT(UNION(VALUES(Real[Dept]), VALUES(Est[Dep])))

Don't forget to relate it back to both your fact tables.
