hi Anonymous

I cannot find how I can attach data. There is a link option but I am unable to open dropbox or google drive here sincethey are blocked by our firewalls. If you give me your email I can send it to you.

my data looks like this

step            count                   opp_date

abc             565464                1/22/2019

abc             464646                 1/21/2019

abc             9886464               1/20/2019

xyz              2355                     1/22/2019

xyz              5646464              1/21/2019

xyz               1254                   1/20/2019

 

For each of these tables abc and xyz, I need to find the daily change. That means for opp_id date 1/22/2019 and table abc, I will perform 565464/(464646-1)

For xyz, I would do for 1/22/2019 -->  2355/5646464-1

Similarly for more tables.

The matric that I have created in powerBI looks like this. How can I subtract value for date 1/22/2019 from date 1/21/2019 for each step?

HI Anonymous,

 

You can try to use following measure to calculate diff between current and previous value:

Percent = 
VAR currDate =
    MAX ( Table1[opp_date] )
VAR prevDate =
    CALCULATE (
        MAX ( Table1[opp_date] ),
        FILTER ( ALLSELECTED ( Table1 ), [opp_date] < currDate )
    )
RETURN
    DIVIDE (
        CALCULATE (
            SUM( Table1[count] ),
            FILTER ( ALLSELECTED ( Table1 ), [opp_date] = currDate ),
            VALUES ( Table1[step] )
        ),
        CALCULATE (
            SUM ( Table1[count] ),
            FILTER ( ALLSELECTED ( Table1 ), [opp_date] = prevDate ),
            VALUES ( Table1[step] )
        ),
        BLANK()
    )
