Secondary Resource Scheduling (SAP Library - Process Orders (PP-PI-POR))

Secondary Resource Scheduling

Use

The system uses this function in master recipe or process order scheduling to determine the start or finish dates of the secondary resources.

Prerequisites

You have chosen a scheduling type that allows secondary resource scheduling (see Scheduling Type).

Secondary resources are not scheduled in scheduling types with the Only capacity requirements indicator. The scheduled start and finish dates of the recipe or order are used for these resources.

A control key has been assigned to the secondary resource in which the Scheduling indicator has been set (see Control Key).

If the Scheduling indicator has not been set in the control key, the system uses the dates of the superior operation or phase for the secondary resource.

Features

The system uses the following data to determine the secondary resource dates:

The dates of the superior phase or operation

The offset between the start and finish dates of the phase/operation and the secondary resources, which has been defined in the detail data of the secondary resource (see Definition of Earliest and Latest Dates)

The following rules apply in secondary resource scheduling:

A positive offset is added to the corresponding phase or operation date, that is, the secondary resource date is after the reference date
A negative offset is subtracted from the corresponding phase or operation date, that is, the secondary resource date is before the reference date

If no offsets have been defined for a secondary resource, the system uses the relevant phase or operation date as the secondary resource date.
