Seasonality on measure

[vanweelden]

Hello,

For each year our company determines an expected seasonality for coming year(s).

I want to apply that on a calculated yearvalue, whereby if seasonality is M, the yearvalue has to be divided by 12. Is seasonality S, then apply seasonality by given value according table.

Eaxample:

Costs 2024 = sum (Costs 2023) * 1,05

Split Costs 2024 over the months of 2024 by the given seasonality (M or S).

How do i achieve this? This is my testfile which also shows the desired outcomes (jpeg):

Is seasonality S, then apply seasonality by given value according table.

In which table? Seasons?  You want to divide the month value by the sum of all month values, and then multiply with the year cost?  Will there be a compounded 5% increase in 2025?
