## Comparing two values in two visual

Currently I have two different matrix one which has current month data and one with previous month data (the months r not actual month dates but business month date logic attached as image). I want to subtract current collection and previous collection (Sum of total amount from collection table) and show it in a third matrix  or in first or second matrix (eg :26th monday value from first matrix - 29th Monday value from second matrix this is needed for each row in the visuals(Basically like  a cell to cell subtraction in excel like A4-B4). A simple measure with Current collection - Previous collection is not working because of how the model is . Have attached some reference images . I am quite new to power BI and might be missing something obvious so any suggestion is welcome.

I was able to do this calculation using the given measure hope it helps out someone in the future

Please note I added this measure into the Current Month matrix and the measure calculation  is based on that .

@Akhil410 , Usually in such cases either on the period start date or with YYYYPP we create a rank and try to create this month vs last month

With a separate year period table say Date

new column

Period Rank = RANKX(all('Period'),'Period'[year period],,ASC,Dense)

measures

This Period = CALCULATE(sum('order'[Qty]), FILTER(ALL('Period'),'Period'[Period Rank]=max('Period'[Period Rank])))
Last Period = CALCULATE(sum('order'[Qty]), FILTER(ALL('Period'),'Period'[Period Rank]=max('Period'[Period Rank])-1))

@amitchandak Thank you for your response . I already have index columns created in current month and prev month table(both are of 2021) using RANKX function can that be used somehow as index 1 in both the tables are the ones to be compared(similary each index) . Also could you  plz provide some more insight on this year table concept I couldnt quite grasp it.
