This can be done in 2ways. If you need variance only for display in the layout, can go with macros. If variance needs to be stored in the cube, use FOX formula.
Macro:
Go to tools-> macro-> SAPAfterDataPut ->Edit
write the code to calculate variance as difference of plan and actual. In the third screen of the layout builder, click on MSExcel Settings tab, check the box for SAPAfterDataPut so that macro will run automatically when you execute the layout.
FOX:
Keep keyfigure name in fields to be changed.
{Variance KF} = {Plan KF} - {Actual KF}
