Reallocating revenue booked in one month over the year

Hey Experts,

I wanted to ask if its possible to reallocate revenue booked in one month to a secondary cost center over the year.

Months done in FI are closed and CO is still open, but to keep the consistency of FI reports the idea was to use secondary cost elements to split the amount between months (period of 1 year) to get an accurate report for CO.

I wanted to ask if this is possible and what kind of advantages or disadvantage this has?

Is there an easier or better alternative ?

Best regards,

Arthur
