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)
