## Measure to substract value within a column

Hi there,

Is there anyway I can use a measure to calculate values in the same column?  I have the column from date, to date and payment, need a measure to calculate the increase value as shown below.  Please advise.

Hi, @sraj

There's only one bug with your formula:

Are these two columns the same? If it doesn't work, your actual data may not satisfy the logic in the code,

I have a simple method, you need to add a index column in power query first.

Then create a measure like this:

``````Inrease =
VAR a =
MAXX (
FILTER (
ALL ( kro_EMP_Payment ),
[Index]
= SELECTEDVALUE ( kro_EMP_Payment[Index] ) - 1
),
[PAYMENT]
)
RETURN
IF ( a <> BLANK (), SELECTEDVALUE ( kro_EMP_Payment[PAYMENT] ) - a )
``````

Hey @sraj ,

you can just consider the rows where the TO date is a day earlier than the FROM date.

An approach like this should work as a calculated column:

``````Inrease =
VAR vRowFromDayBefore = myTable[FROM] - 1
VAR vRowPayment = myTable[PAYMENT]
VAR vRowPaymnetDayBefore =
CALCULATE (
MAX ( myTable[PAYMENT] ),
myTable[TO] = vRowFromDayBefore,
ALL ( myTable )
)
RETURN
IF (
vRowPaymnetDayBefore <> 0 && vRowPaymnetDayBefore <> BLANK (),
vRowPayment - vRowPaymnetDayBefore
)
``````

The result looks for me like this:

If you need any help please let me know.
If I answered your question I would be happy if you could mark my post as a solution ✔️ and give it a thumbs up 👍

I dont know why I am seeing this, not sure what I am doing wrong?

Inrease =
VAR vRowFromDayBefore = kro_EMP_Payment[From] - 1
VAR vRowPayment = kro_EMP_Payment[payment]
VAR vRowPaymnetDayBefore =
CALCULATE (
MAX ( kro_EMP_Payment[Payment] ),
kro_EMP_Payment[To] = vRowFromDayBefore,
ALL ( kro_EMP_Payment )
)
RETURN
IF (
vRowPaymnetDayBefore <> 0 && vRowPaymnetDayBefore <> BLANK (),
vRowPayment - vRowPaymnetDayBefore
)
