DAX formulas

[ola1996]

Hello, 

I'm new in DAX and I need some help. I try to create new measure to calculate the amount for my accounts. But the problem is that I have amount from each account by months. Like in the table below.

And I want to see amount from January in April, from February in May, from March in June, from April in July, from May in August, from June in September and so on.

My question is, how can I do it by DAX formulas?

This is very easy on condition that you've got the correct model.

[Balance -3Mth] =
	CALCULATE(
		[Balance],
		DATEADD(
			Calendar[Date],
			-3,
			month
		)
	)

Best

Can you tell me how to create this formula if I want to add vaules from January to March and show it as a sum of March and January and with next months the same situation ?

@Anonymous  I base on three tables and four columns. 

date: Posting_Date (hierarchy: day, month, year) from "General Ledger Entries" table

values: Amount (as a sume) from "General Ledger Entries" table

and accounts from "dictionary VAT' table

I was trying to change your formula for my needs like that 

CALCULATE( 'General Ledger Entries'[Amount]; 
		DATEADD(
			'General Ledger Entries'[Posting_Date].[Miesiąc],
			-3,
			month
		)
	)

but still doesn't working

@amitchandak Sorry, I did't see my mistake 

Here are base table 

That should be the outputs

@ola1996 , can not tell mistake with image, need sample data

[ola1996]

I thing it's impossible because these are data directly from Dynamics 365 BC.
