Subtract two columns

I'm trying to do simple subtraction of two columns.  I'm creating a pay register.  I have a column with earnings, a column with deductions and want to subtract deductions from earnings to create a new column, net pay for each employee.

 

Earnings and deductions come from separate tables.  When I try to subtract these, it always aggregates the amounts, rather than giving me just the amount for each.

 

How do I successfully subtract?

Hi, @adraus 

 

You can try the following methods.

Measure = 
SELECTEDVALUE(_GroupEarnings[_EarnAmount])-SELECTEDVALUE(_GroupDeductions[_DedAmount])
Measure 2 = 
SUM(_GroupEarnings[_EarnAmount])-SUM(_GroupDeductions[_DedAmount])

Both of these measures give the result of subtracting two columns.

If the only connections are the year and payperiod (and presuming they will have same payperiod in both tables moving forward) you could try TREATAS:

 

 

Total =
VAR earnings =
    MAX ( GroupEarnings[Earnings] )
VAR deductions =
    MAX ( GroupDeductions[_DedAmount] )
RETURN
    CALCULATE (
        earnings - deductions,
        TREATAS (
            SELECTCOLUMNS (
                GroupEarnings,
                "Year", GroupEarnings[Year],
                "Payperiod", GroupEarnings[Payperiod]
            ),
            GroupDeductions[Year],
            GroupEarnings[Payperiod]
        )
    )

Hi @adraus 

Try this.

 

 


Let me know if you have any questions.

 

Total = 

var _earn = MAX(Earnings[Earnings])

var _ded = MAX(Deductions[Deductions])

return _earn- _ded

 


If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos 👍are nice too.

I'm not having success.  The new column is showing the same invalid value all the way down.

Perhaps I missed something in the command?

Hi @adraus ,

In order to have data from two different tables they have to be linked in some fashion. 

Here is one way.

Please tell me, is this for a short term project or something else.  Can you share your pbix with me?

If you would share your pbix, or dummy up some values in Excel both for current and expected data. Please copy and paste them into your post, rather than doing a picture, we may be able to help you. 

Please read this post to get your question answered more quickly:
