SAP business 1 MRP module demand variance between running two identical forecasts

[former_member1155655]

Dear all

I need your help in below situations

I have entered the same forecast once by month and once by week but when running the forecast the demand had changed dramatically between by month and by week (Same forecast quantity).

Can you please advise the reason behind this variance, which one is more accurate?

Many thanks in advance.
