Distribute Planning Function(Using Variables)

Hi All,

I'm trying to distribute KeyFigure value between months.

For example:Between Jan2005 and April2005 i want to distribute values.

4000 gets distributed as below:

Jan2005 - 1000

Feb2005 - 1000

Mar2005 - 1000

Apr2005 - 1000

I want user to select from CalYear/month and To CalYear/month from WebInterface dynamically.

But,Distribute from Sender to Receiver planning function is not allowing me to use two variables From and To.

It is allowing me to use only one Variable.

Could u please suggest me how to use two variables in distribute planning function.

Thanks in advance,

Pat.
