Constrained forecast run

[carlos_perez8]

Hi all

Regarding the documentation you can priorizate sales orders over forecast and consider for example customer priorities in contrained forecast run.

But if the constrained forecast run does not consider sales ordes, or you don’t forecast by customer, what is the utility of this planning type?

Hi Carlos,

the order-based heuristic strictly plans demand by demand. Therefore it is needed to have a sequenced list of demand elements. The prio rules must be used to do that.

Hi Carlos -

In simple understanding, the constrained fcst run will take the input of you consensus plan and comes up with the constrained supply. This constrained quantities is then copied to the allocation quantity using a copy operator which is taken as the input for the confirmation run so the allocated quantities (which are the results of the constrained run) gets "confirmed". Obviously, you end up using the sales order and the unconsumed fcst in the confirmation run but note that the net demand still remains the same as that of the total fcst considered during the constrained fcst run.

You may also completely ignore the constrained fcst run and the copy to allocation quantity and choose to go directly to the confirmation run which will consider your unconsumed fcst and the sales orders.

Hope this is what you were aiming at understanding,

Thanks,
