Levels of Scheduling (SAP Library - Material Requirements Planning (PP-MRP))

Levels of Scheduling

Use

The scheduling level defines which scheduling data will be used for lead time scheduling.

Integration

You use rate-based scheduling in repetitive manufacturing.

You use rough-cut scheduling in demand planning and preliminary planning.

Features

You can carry out lead time scheduling at three different levels:

Detailed scheduling uses the times recorded in the routing. The execution time is subdivided into the operation steps, setup, processing and tear down.

You can also define additional parameters for detailed scheduling such as reduction, and the scheduling type (backward, forward) in Customizing for MRP.

You use rate-based scheduling in repetitive manufacturing. This type of scheduling uses the times recorded in the rate routing.

Rough-cut scheduling procedures usually use the scheduling data from the rough-cut planning profile. This type of scheduling is used for a higher level planning level (sales and operations planning) to gain an overview of the capacity situation. The rough-cut planning profile represents an overview of the total BOM structure.

In MRP, you usually use the detailed scheduling procedure.
