In-House Production Time: Dependent on Lot Size (SAP Library - Material Requirements Planning (PP-MRP))

In-House Production Time: Dependent on Lot Size

Use

You use lot size dependent in-house production time if the processing time controls production to a greater extent than the lot size independent times, for example, queue time or setup time.

Prerequisites

You have maintained the following times in the material master (Work scheduling view):

Setup time
Processing time
Base quantity of the processing time
Interoperation time

Features

The setup time and the interoperation time are both independent of the lot size.

The setup time is the number of days that are necessary to set up and tear down machines that are required to process the material.

The interoperation time is the sum of the wait times, queue times and move times as well as the float before and after production.

On the other hand, the processing time depends on the lot size and is adapted correspondingly to the lot size in the order. The base quantity is used as the basis for calculating the processing time dependent on the lot size. The processing time is generally made up of machine times and labor times.

The system determines the lot size dependent in-house production time from both times depending on the lot size in the order.

The floats (for example, float before production, float after production) are not included in the calculation of the in-house production time, but actually form part of the in-house production time. The total floats are maintained through the interoperation time.
