Dear All,

How can I calculate of last three months average sales based on my selection?

As an example,if I select Aug-18 then calculated average sale should be of '(June-18 + July -18 + Aug - 18)/ 3'

Thanks in advance

ok, I see your problem..

you were making selections on FMonthName and you didn't detach it from the set analysis:

try this exact expression on your AvgSales formula:

sum({<FMonthName,FMonth={">=\$(=Max(FMonth)-2)<=\$(=Max(FMonth))"}>}SecNetAmount)/3

Hi,

the solution depends on the output you're looking for

do you want to display the last three months on the table with the average on every cell ? do you want to display the average on a textbox ?

would you be able to describe the expected output ?

Hi, it can vary based on date formats, if you have a master calendar... but it can be something like:

Sum({<Date={">\$(=AddMonths(Max(IdFecha),-3))<=\$(=Max(IdFecha))"}>} Sales)/3

Ruben already gave you the solution, just tell us what is the exact format of the field on which you're making your selections (month year maybe)

Actually i dont have any Date field... only month and year. As an example : 201801,201802,201803 and so on.... so i did not find solution on Ruben's expression....

Ruben talks about Date-related fields, like the one you're using

let's say your year month field is called: YearMonth.. try this (based on the format you shared above):

Sum({<YearMonth={">\$(=Date(AddMonths(Max(Date#(YearMonth,'YYYYMM')),-3),'YYYYMM'))<=\$(=Max(YearMonth))"}>} Sales)/3

If you don't mind, can you please explain me the formula......

Its consider only one value which i select....but it should also calculate the value of previous two months....

=Sum({<YearMonth={">\$(=Date(AddMonths(Max(Date#(YearMonth,'YYYYMM')),-3),'YYYYMM'))<=\$(=Max(YearMonth))"}>} SecNetAmount)/3

but also need to consider the sales value of previous two months
