Actuals and forecast totals in next tab and another story

Hello,

I have data Actuals coming from SAP BYD and forecast done in SAC. For now, i tried accumulative sum(Actuals+Forecast) but i cannot take it to next tab and another story of the same data model.

I want the totals of Actuals and forecast in the next tab and also in another story. How to make it possible in SAC. Does anyone have a solution for this?

Thanks in advance.
