I have a table called Sales in which I have entry of day wise client ID wise sales since 2019. This table is called "SalesMaster".
I have another table in which the entry of money collected day wise and client ID wise is mentioned.
Scenario - If a sales happens in suppose month of Feb 2021, the money can be collected in Feb 2021 or in March or in April.
Problem - I need to calculate that how much of the money collected is from the current month of sales, client wise.
Example - If Client C01 purchased goods of INR 5000 in Feb 2021 and paid 500 in April 2021.
Another client C02 purchased goods of INR 3000 in April 2021 and paid 1500 in April 2021
So In April 2021, the total collection is INR 2000 but INR 500 (of client 1) is of old month.
I need a mesure called -CurrentMonthSalesCollection which will give the value of INR 1500 and OldMonthSalesCollection as INR 500.
I hope I have been able to explain the problem correctly.
