Collective PO: Seasonal Procurement
Scheduling
With this function, you can use scheduling in Seasonal Procurement to schedule a collective purchase order.
You have configured the grouping of items in Customizing for Seasonal Procurement under PO Processing → General Settings → Process Control Table for Grouping.
· When you create a collective purchase order, you can define whether the system is to use general scheduling or scheduling in Seasonal Procurement.
If you use scheduling in Seasonal Procurement, the system calculates dates according toscheduling in purchase order monitoring. The system also automatically performs grouping based on the delivery date. During grouping, it transfers the delivery date and all grouping settings for the standard purchase order.
For more information about
calculating dates in purchase order monitoring, see
Scheduling.
· If you use Seasonal Procurement scheduling, the system always determines the source of supply (vendor) irrespective of your settings, because both the vendor calendar and the purchase order and delivery frequencies are included in the schedule calculation.

You can process the generated collective purchase order subsequently but you cannot change the vendor that has been determined.
On the SAP Easy Access screen, choose Logistics → Retailing → Merchandise Logistics → Merchandise Distribution → Collective Purchase Order → Create.
You make all the settings for the collective purchase order, set the Seasonal Procurement indicator on the Seasonal Procurementtab page under Scheduling and Grouping, and generate the collective purchase order.
