Maintenance of Period Profile for Grouping Component Reqmnts

Use

In this Customizing activity for the Rapid Planning Matrix (RPM), you define the period profiles for the grouping of the component requirements that the RPM has determined.

For components that you have set for grouping in the material or product master ( Always coll. requirements field), the SAP APO uses the results from the matrix to calculate the total dependent requirements per period for a component. You can use a period profile to define the periods as you require. Requirements grouping by period has the advantage that the system does not have to generate a procurement element for each individual dependent requirement. It is only necessary to generate one procurement element for all dependent requirements that fall within a certain period.

You use this procedure for components that are not directly intended for a particular sales order.

Prerequisites

You have maintained the factory calendar for a location.
You have created a line resource, and a shift sequence for this resource.

Features

You maintain the period profile independently from the location and the factory calendar. You assign the period profile to a product by entering a period profile ID in the product master, in the Period Profile field ( Demand tab page). The system uses the assignment to determine the necessary line resources, and thereby the valid shift sequence and factory calendar, for the resources. The system uses the entries for the period profile, the shift sequence and the factory calendar to determine the periods in which the dependent requirements are to be grouped.

If you wish to simulate the effect of a period profile on a particular resource, choose the Simulation for a resource function key. The system then calculates the time bucket for the selected resource, based on the period profile. See also: Calculation of Table of Periods for a Resource

Define periods

For example, you can use a period profile to determine that the dependent requirements are to be grouped monthly in the long-term horizon, weekly in the mid-term horizon and daily or by shift in the short-term horizon. In addition, you can break down a shift into subdivisions. For example, each hour should be the start of a new period, in which case the dependent requirements are grouped on an hourly basis. To do this, you enter the number of smaller shifts into which a shift is to be divided, for instance hourly grouping, in the lowest line of the period profile. In addition, you must maintain the table in the lower screen area. In the Offset field, enter a time offset for the subdivision. For example, if the requirements are to be grouped hourly, enter 1:00:00 first, then 2:00:00 in the second row, and so on. The system then calculates period 1 as 06:00 to 06:.59, period 2 as 07:00 to 07:59, and so on.

However, you can also set just daily groupings or just shift groupings.

Standard period profile

The period profile SAP_PPROFILE_DEFAULT is proposed as default. During the first planning run, the system checks that you have created a period profile and have assigned it in the product master. If you have not done so, the system automatically uses the period profile SAP_PPROFILE_DEFAULT. If you have selected Always coll. requirements in the product master for the components and have not entered a user-defined period profile in the product master, the system always uses this period profile when grouping the component requirements.

Activities

To create a period profile, choose Customizing for Production Planning and Detailed Scheduling (PP/DS) and then Start of the navigation path Rapid Planning Matrix Next navigation step Maintain Period Profile for Grouping of Component Requirements. End of the navigation path

The following example shows how to maintain a period profile:

The dependent requirements are to be grouped monthly in the long-term horizon, weekly in the mid-term horizon, and daily or by shift in the short-term horizon. For this, you set the period profile as follows:

Length	Unit of Length	Unit of Aggregation
		Year
1	Month	Month
1	Month	Week
1	Week	Day
1	Day	Shift
		Finer Breakdown

The system interprets the period profile starting from the bottom and working upwards. Starting from the planning date, the periods are to be shifts for the first day, then days for a week, and then weeks for a month. The last period is to be a month.
