Macro for Adding key figure for defined days

Hi experts,

I have to write a macro where I have to calculate Final net forecast key figure at day level.

I have FORECAST key figure calculated at day level & another key figure to store cyclic days.

Now I need to add Day level FORECAST key figure for number of cyclic days.

e.g. we have daily FORECAST as

Cyclic days as 5.

Then CYCLIC DAYS DEMAND =

Then we have Safety days demand = safety days supply * STAT FORECAST key figure at day level

e.g. Safety days supply in product master as 4 & STAT FORECAST AT day level as 16.667

SAFETY DAYS DEMAND = 66.668

Then FINAL NET FORECAST = 63.717 + 66.668 / (4+5) = 14.49   --> (4 safety days supply & 5 cyclic days supply)

I attempted to use loopcounter method for this. But seems not working.

Can you pls help with it?

Below is the code:

B1, B2, B3 in sequence

Thanks,
