BPS - Distribute with Reference data sender 2 reciever functionality

Hi All,

I'm looking for some documentation on this planning function(Distribute with reference data / from sender to reciever).When I run this function I have problems finding the Reference data,although I have defined the refernce data correctly and am using the # for the characteristics.

Is it possible to override a characteristic while executing this function.? for example you are distributing values form region level to line of business level,can you change the allocation flag(another characterstc) while executing this.?

Any documents with some Examples and guidelines of setting up Reference data will be very useful.

Thanking everybody in advance.,

Sudz.
