 Scheduling for External Procurement

Implementation Options

Only the basic dates for procurement elements are determined for external procurement.

Prerequisites

  • You have entered the purchasing processing time (workdays) in Customizing for MRP either in Plant parameters or in the IMG activity Define external procurement .

  • You have determined the planned delivery time (calendar days) in the material master (view MRP 2 ).

  • You have determined the goods receipt processing time (in workdays) in the material master (view MRP 2 ).

Process Flow

In the MRP and forecast-based planning procedures, backward scheduling is used to determine the basic dates. In reorder point planning, however, the basic dates are determined by forward scheduling.

  • For the planned order this includes the order start date and the order finish date.

  • For the purchase requisition, the following dates are determined:

  • The delivery date (which corresponds to the order finish date)

  • The release date (which corresponds to the order start date)
