divide two column values in a matrix

I am replicating an excel report. in PowerBI

columns that I have in my database

step

sub_program_code

count

description

opp_id_date

patient_count

Excel view:-

B= step

C=sub_program_code

D= count

E = Description

F = opp_id date (today-6)

= opp_id date (today-5)

= opp_id date (today-4)

= opp_id date (today-3)

= opp_id date (today-2)

= opp_id date (today-1)

= opp_id date (today)

M= % daily change [opp_id date (today)/opp_id date (today-1)-1]

How can I get value for column M in PowerBI?

Hi @Mab,

Please share some sample data so that we can use it to create visual and test to coding formula.

Re: divide two column values in a matrix

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?

Re: divide two column values in a matrix

HI @Mab,

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()
)
```
