Calculation groups - gap calculation

[MarcinSz]

Hi all,

I have an issue with calculation groups. I've created calculation groups for P&L lines and put them to Matrix. Please have look at the snapshoot.

My problem is that when I am calculating a gap between forecast and previous forecast every data looks ok, except %Gross profit.

I would like to see here is -63,6 instead 90,9%. It's looks like calculation are based on ( Gross profit(FCT-PFCT) / Revenue[FCT-PFCT] ) instead of ( %Gross profit[FCT] - %Gross profit[PFCT] ).

Does anyone able do help?

I attached also pbix file. https://www.dropbox.com/s/5fy1u1vvpt0yie6/Calculation%20Groups%20Sample.pbix?dl=0

BR,
