Subtraction of two columns not showing the correct values

[MP-iCONN]

I have an issue with two columns I am trying to subtract from.

One column is called Required Qty and the other is called Original Blanket Qty.  

I created a measure called Unscheduled Blanket Qty:

Unscheduled Blanket Qty = CALCULATE(SUM('Sales Orders'[Original Blanket Qty])) - SUM('Sales Orders'[Required Qty])

As you can see from the screenshot the 2nd line does NOT appear to be subtracting correct.  I tried a bunch of different options but not sure how to get the math to be correct.

Any help is greatly appreciated!

Thank you.

@MP-iCONN 

maybe you can try

SUM('Sales Orders'[Original Blanket Qty]) - SUM('Sales Orders'[Required Qty])

you can use measures to display the first two columns to check if returns the correct result and do the calculation between these two measures.

Same issue.

I did a SUM measure for both Blanket Qty and Required Qty and then added in my Unchscheduled Blanket Qty with the SUM('Sales Orders'[Original Blanket Qty]) - SUM('Sales Orders'[Required Qty]) measure and still the same value where it is not subtracting the 1820 from 910 correctly.

@MP-iCONN 

pls try this

measure = max('Table'[orignial blanket qty])-max('Table'[rquired qty])

Measure 2 = sumx('Table',[measure])

[MP-iCONN]

I tried this and the MAX seemed to work for measure1 (Unscheduled Blanket Qty) but then I did the SUMX of that Measure1 and still off.

Unscheduled Blanket Qty = MAX('Sales Orders'[Original Blanket Qty]) - MAX('Sales Orders'[Required Qty])

Unscheduled Blanket Total = SUMX('Sales Orders',[Unscheduled Blanket Qty])

Thank you for your help so far!
