and olny the last month f.e I had 2700000 kg of CPRS in January, i need the same value for fabruary

You'll need a date table to do this properly. Then the following measure will give you the previous month sales. The filter context of the table/matrix will keep it to just items of the same Type.

=CALCULATE(
	[Total Sales],
	PREVIOUSMONTH('Calendar'[Date])
)

Try like this:

= CALCULATE(

        SUM( 'Table'[kGS] ),

        ALLEXCEPT( 'Table', 'Table'[Type] ),

        'Table'[Month] = EARLIER( 'Table'[Month] ) - 1

)

Can someone explain how the post marked as a solution works? My understanding of EARLIER is it has nothing to do with dates, but with contexts within a measure.

When I tried the measure marked as a solution, I get the following error, which is similar to what I expected.

Calculation error in measure 'SalesData'[measure 1]: EARLIER/EARLIEST refers to an earlier row context which doesn't exist.

@edhans

you're probably using it in a measure which has no row context instead of a calculated column as the OP requested:

Ahhh... thanks. I never create calculated columns unless I need it in a measure, and even then, I tend to push it back to Power Query, so my bias there missed that part of the question. 🙂
