[samihuq]

Hi There,

I have got two tables. Table A has  Date and Quantity Column as bellow:

Date	Qty
01-Jun-15	12246443
02-Jun-15	12737355
03-Jun-15	11901529
04-Jun-15	11574494
05-Jun-15	13583459
06-Jun-15	11980839
07-Jun-15	11727211

And Table B has bellow Rate Table:

Date	Rate
01-Jun-15	$0.015
05-Jun-15	$0.016
10-Jun-15	$0.017

Now how do i join them so that i can calculate the revenue?

Thanks,

Sami

Is your pricing a change schedule?  For instance the price is  $0.015 for any orders placed between 01-Jun-15 and 04-Jun-15, at which the rate changes to $0.016 for the next period?  We need a little more information to help you out properly.

You will want to create a separate Calendar/Date table (that can have nice columns like Year-Month, etc).  You will create relationships from the Calendar[DateKey] to each of the data columns in your data/fact tables shown.

When building reports, you will use columns from the Calendar table, which will magically filter BOTH of the tables you have here.

There is no way to delete replies here!?  My answer was... not exactly on target 😞

You need a way to calculate the "most recent rate".  That is the last date in rate table, which is less than (or equal?) to the date in your quantities table.

Maybe something like... ?

=CALCULATE(
     LASTNONBLANK(Rates[Date], MIN(Rates[Rate]),

     FILTER(Rates, Rates[Date] <= MAX(Quantites[Date]))
)
