Measure to Deal with Negatives in Calculation

Hi, Thanks in advance.

I couldn't find a way of uploading a file to the forum. The link below is a google drive link to a copy of the file.

In a previous post:-

I was kindly supplied with a measure to do the first calculation I need.


Measure =
var _a = ALLSELECTED('Table'[Work Type])
var _b = MAX('Table'[Row])
return SUMX(FILTER(ALL('Table'),[Work Type] in _a&&[Row]<=_b),'Table'[Amount]-'Table'[Available])
Giving the results in the example below
row 1 Measure is Amount - Available  (12 - 2160 = -2148.00)
row 2 Measure is Row 1 Measure (-2148) + Row 2 Amount (85) - Row 2 Available (2160) = -4223
row 3 Measure is Row 2 Measure (-4223) + Row 3 Amount (1660) - Row 3 Available (2106) = -4723

I need an additional column which deals diffrently with negatives in the measure column. Therefore the 'New Measure' column instead of -negative numbers uses a 0 and only uses positive numbers in the calculation. See illustration below.



I hope this makes sense.





That's unfortunately exactly the point. The result cannot be modified by filters.

That selective addition is not something you can do in DAX.  You can use List.Accumulate in Power Query for this but that will result in a column, not a measure.

Thanks @lbendlin . Not sure what list.Accumaulate is, will have a look. I'm not sure it matters if the result is a column so long as it does the calcultion and can be filtered by a slicer.

That's unfortunately exactly the point. The result cannot be modified by filters.

Thanks for letting me know. I'll have to think of another way of doing it.
