Calculated Column - 2 Tables

[kault]

Looking for help with a calculated column between two different tables.

The end goal is for the calculated column to be: (Hours at Completion) - (Travel Time)

Hours at Completion is on one table, Travel Time is on a different table.

The relationship between the two tables is Many:1.

How can I accomplish this?

Although you can try to add column in the table that is on the many sides by using DAX function called RELATED to refer column from one side.

I would ❤ Kudos if my solution helped. 👉 If you can spend time posting the question, you can also make efforts to give Kudos whoever helped to solve your problem. It is a token of appreciation!

Table 1:

Project Code	Hours at Completion
Project A	90
Project B	80
Project C	102

Table 2:

Project Code	Travel Hours
Project A	5
Project B	0
Project C	4

Desired Output: (Hours at Completion - Travel Hours)

Project Code	(Hours at Completion - Travel Hours)
Project A	85
Project B	80
Project C	98

If Table 1 is on the many side, you can use this expression to get your result

NewColumn = Table1[Hours at Completion] - RELATED(Table2[Travel Hours])

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.
