Dynamic column name in measure

Hello,

I have the following table with accounts and value for each month of the fiscal year. Data is in French, but the problems is the same : I want to create monthly measures, where I need to ping each column in turn.

For example, I want the measure A as the sum of accounts 101300 and 104100. I would then have to create a measure per column, which is not ideal. My aim is to have a dynamic column name and a single measure that goes something like :

CALCULATE(SUM([Month]);Accounts="101300").

Do you have any clues ?

Thanks
