hello thanks for reply This is my pbi file!As-fix_XbK9zhHfGq-OLEKAkwxFp?e=Ev6G6h 

Basically what am trying to do is to calculate monthly km used and monthly fuel consumed for this period

For example Nissan sunny rent started on 9 october 2023, and every month on 9th day rent is paid, also allowed kms per months are 2500 km

So from 9 october till 9 november this is 1 months of rental, so on 9th of November I record how many km used, also I have a table for fuel consumption each type I refuel the car with how many liters

So what I want basically for each months to see the km used , but as I record on 9 november, this actually are October kms used as from 9 october to 9 november car was used

And remaining km are “allowed km-km used”

Also how I can write a dax to calculate fuel from 9 october till 9 november?

Also how on my table for november sum of km used should be actually october, how to do that?

Or should i initially change my table?
