Demand-Driven Procurement
SAP Best Practices for Retail
Purpose, Benefits, and Key Process Steps
Purpose
 This scenario begins with the required planning steps. The forecasting processes and different consumption-based MRP
procedures. The supply source determination schema in SAP R/3 is then outlined in brief and the various options
explained. The Purchase Order process shows you how to work with the Planning Workbench. Order optimizing
comprises quantity optimizing, investment buying, load building and goods receipt capacity check. The last section shows
you how vendor evaluations can be used to optimize goods procurement.
Benefits
 Alongside article-specific inventory management, the SAP R/3 System provides an accurate data basis for using the
comprehensive range of requirements planning methods. The main task in requirements planning is to monitor stocks and,
in particular, generate automatic order proposals for purchasing.
 With the planning workbench, extensive functionalities for order optimization and vendor evaluation you can handle the
whole process for demand-driven procurement.

Goods Receipt Capacity Check
Up to now, there was no check for sufficient capacity for the delivery date of a
planned delivery in the goods receipt area of a warehouse. If the goods are delivered
to a warehouse door that does not have any free capacity, there can be a bottleneck
in the goods receipt area of a warehouse. At the same time, another warehouse door
might have enough capacity.
Advantages for Retailer and Vendor:
 Taking the goods receipt capacity into account prevents potential bottlenecks.

The vendor's delivery date planning utilizes the capacity of the retailer's goods
receipt areas.

The vendor can schedule the deliveries better since the planned time window for
inbound deliveries is binding.
