Subtracting Columns

BICrazy — Fri, 11 Sep 2020 09:44:07 GMT

Hi there Power BI Community.... I need your help, please.

I need to create a measure that subtracts the preceding column from the next and displays the answers only (in bold red below).

Example
1st row:
May-19 14 - 6 = 8, 6 - 5 = 1, 5 - 4= 1, 4 - 4= 0, 4 - 4= 0

2nd Row
Jun -19 158 - 123= 35, 123 - 115= 8, 115 - 101 = 14

and so forth for each row and column.

Here's a Matrix view of the data.

Here is your measure:

Measure = VAR CV = MAX(Table1[Value]) VAR D = SELECTEDVALUE(Table1[Day])+1 RETURN CV- CALCULATE( MAX(Table1[Value]), Table1[Day] = D, ALLSELECTED(Table1[Day]) )

Thanks Fowmy,

The measure worked like a charm. I just inserted the portion to accommodate the blanks on my data set.

Previous Index Policies = VAR CV = [Bank Submissions] VAR D = SELECTEDVALUE('Ongoing & Unpaid Data Revised'[Index])+1 RETURN CV- CALCULATE( [Bank Submissions], 'Ongoing & Unpaid Data Revised'[Index] = D && CV <> BLANK(), ALLSELECTED('Ongoing & Unpaid Data Revised'[Index]))
