Scheduling (SAP Library - Consumption-Based Planning (MM-CBP))

Scheduling

Use

Scheduling is carried out in MRP after the system has calculated the quantity to be procured in the lot-size calculation. As the materials planned using consumption-based planing are externally procure, the following description is of scheduling for external procurement.

Scheduling determines the order start and the order finish dates of the procurement elements.

Prerequisites

You must define the processing time for purchasing in workdays either in Customizing for MRP, in the plant parameters or in the workstep, external procurement.

You must define the planned delivery time of the material in calendar days in the material master record (MRP 2 view).

You must define the goods receipt processing time in workdays in the material master record (MRP 2 view).

Features

In forecast-based planning, the basic dates are calculated in backward scheduling, in reorder point planning, they are calculated in forward scheduling.

This is the order start date and the order finish date of the planned order. The opening period is also taken into consideration in scheduling for the planned order.
The following dates are calculated for the purchase requisition:

Delivery date (corresponds to the order finish date)
Release date (corresponds to the order start date)
