Predicting Purchasing Demands

Example:

We purchase feather meal in a pallet of 50 bags (that is one stock item), we then do production orders to create single bags of feather meal, and that feather meal is also used in mixes.

If we want to purchase pallets of feather meal once a year, how do I tell what my demand is based on past sales orders of all forms of feather meal and all mixes that feather meal is used in? We have BoMs set up for all of this data.

On a second note this is our first sales season with Acumatica so we do not have sales history in Acumatica. Is there a way to put that information in Acumatica to help calculate that total needed?

I thought Forecasting was the solution for this but it doesn’t seem to be (but maybe I don’t understand forecasting well).

Thanks!!
