How to calculate in future years&periods using on-demand rules

Summary:

Hi,

we are trying to calculate depreciation and write it into future periods using on-demand calculation. I understood, that by default, a runtimeprompt for Year and Period is defined which I am forced to use.

The question is: how can we calculate values for future periods? what are the typical workarounds. My understanding is I am not allowed to add the Year into the fix and not left side of the equation. Since we need some logic (if statements), a datacopy seems not useful

The calculation we perform is planned to be outside the normal P&L and consolidation and currency conversion logic.
