Manual accrual in Rebate

Hi thr,

I am trying to create a final settlement for a rebate and when I execute final asettlement, it takes me to a screen where it shows what amount was accrued aganist each condition etc. When I try to increase the amount, it lets me do it and there is no check on it. I can change a value of 2K to 10K and it doesn't stop me.

Could someone please explain me this behaviour of SAP. Its seems very strange to me.

Thanks very much !!
