Formula

can you write how to have be?

Try this out
2Sale2s =
VAR _total =

Calculate(

SUM('Planam'[Sales]),
Filter('Planam','Planam'[month] = Earlier('Planam'[month]))

)

var _val = 'Planam'[Sales]
return
_val/_total

maybe you know, how to write formula, then my data is in table for example: 

a result I get Sales 2022 using a different formula  %CT Sales 2022  this this column comes from SALES 2022

how do I get the measure so I can use it for other calculations?

You can use that column values as mesure values and can use it in other visuals.

but I want to get a separate percentage formula, make a new measure

Hi Augustas-ase 

Have you solved this problem? If yes, you can accept an appropriate reply as solution or post your own solution. If not, you may refer to my sample file attached at bottom. Usually providing some sample data or sample file will make other users understand your data and expected result better. 

If you have a column [Sales] in table 'Table', you can try a measure like below. 

% of Sales = DIVIDE(SUM('Table'[Sales]),CALCULATE(SUM('Table'[Sales]),ALL('Table')))

If you already have a measure like [Sales Measure] which calculates the sum, you can create a new measure like 

% of Sales 2 = DIVIDE([Sales Measure],CALCULATE([Sales Measure],ALL('Table')))
