Specifying a Propagation Definition for Characteristics

Use

The Characteristics Propagation screen is divided into two work areas:

Left-hand work area: View of the various PPM nodes (components) to which a class is or can be assigned.

Right-hand work area:

Below: Detailed view of components that were selected on the left, and the various aspects (value assignments, requirements, parameters), that need to be considered in characteristics propagation.
Above (group box): The default value assignments and requirements, as well as the rules for individual components of the PPM plan are defined here.

Prerequisites

For more information, see Starting the Characteristic Propagation.

Procedure

The workflow runs from left to right.

Work area (left) - PPM Components for Selected PPM Plan

In this section, you assign classes to the individual components contained in the current PPM plan. The work area contains tab pages to be used as follows:

Overview - to display and assign classes to all components required by the plan

Plan Classification – to display or classify the PPM plan

Components of Receipts – to display and assign a class to the product receipt

Components of Requirements – to display and assign a class to the product requirement

Activities - to display and assign classes to the activities entered for the current PPM plan

Operations - to display and assign classes to the operations entered for the current PPM plan.

If a class has not yet been assigned to the component, choose Propagation à Propose Classes.

The default class is proposed automatically. All products in logical components are assigned to classes (pegging) and all resources are assigned to an active class (block planning).

Note

To view the default value assignments for the selected component, choose Propagation à Standards.

Work Area (Right) – Detail View of Selected Components

In this section, you propagate the value assignments and requirements for the components you selected in the left-hand work area. The table header indicates the component currently selected.

Tab: Value Assignments

Column	Procedure
Required field	The system automatically generates the information from the class definition.
Characteristic	The system lists all the characteristics that have been assigned to the classified component.
Value assignment used	Set an indicator if the characteristic of the selected component is to be passed on to another component as a value assignment. Only possible if you have selected a product requirement (receipt node).
Value assignment set	Set an indicator if the characteristic of the selected component is to be adopted as a value assignment. Only possible if you have selected a product requirement or an activity (requirement node).
Source type	You can change the characteristic value assignment by entering one of the two types. 'S' (copy characteristic to other component) 'M' (use macro)
Data source	[Display function] The data source indicates the source of the value assignment of a characteristic in the current component.
Macro	If 'M' is specified as the source type, you access a macro which provides the value assignment for the appropriate characteristic in the component. You can expand the context menu by double-clicking on it, and the relevant macro will appear. See Creating Macros.

Tab: Requirements

Column	Procedure
Required field	The system automatically generates the information from the class definition.
Characteristic	The system lists all characteristics that are assigned to the classified component.
Requirement set	Set a flag if the requirement for the characteristic of the selected component is to be changed dynamically.
Value set or mapping interval	If the requirement is based on nominal characteristic types, a ‘ü ‘ is displayed which indicates that entry field is in display mode and the entry cannot be changed. If a standard value has not been maintained, you can make a selection here.
Source type	You can change the characteristic value assignment by entering one of the two types: 'S' (copy characteristic to other component) 'M' (use macro)
Data source	[Display function] The data source indicates the source of the requirement for the characteristic in the current component.
Macro	Here you access a macro that provides the valuation for the appropriate characteristic in the component. You can expand the context menu by double-clicking on it, and the relevant macro will appear. See Creating Macros.

Tab: Parameters

The planning parameters for the product displayed are set during the value assignment.

Column	Procedure
Set for	Displays the specific product for which the macro is to be developed.
Macro	Enter a valid name for the macro. Result: If it already exists in the system, it will be used now. If it does not yet exist in the system, you can create a macro in the subsequent dialog box. See Creating Macros.
Macro description	You can add a description of the macro here.
Description	[Not relevant]

Group Box: Component Details

Displays the component and the assigned class.

Standard Value Assignment

You can assign values to characteristics for receipt and demand components, as well as activities.

To assign a value to individual characteristics, choose Standard Value Assignment.

The Default Value Assignments for Components dialog box then appears.

The characteristics assigned to the class are entered as default value assignments. Default value assignments are used if no new value assignments are created as a result of propagation, or they can be mixed with the results of the propagation.

Standard Requirement

The characteristics for receipt and requirement components can be saved as requirements.

To set requirements for individual characteristics, choose Default Request for Component.

The Default Requirements for Component dialog box then appears.

For more information, see Characteristic Value Assignment and Requirement.

Rules

If you selected a logical component for receipt or requirement, you can also define rules to use when the product selection is prioritized. This also applies to product selections for the logical component and to the mode for the logical component with respect to the activity.

Click the Rules button to go to the Maintain Rules screen.

Tab: Rules

Assign a rule number.

When rules are defined for the logical component, the number assigned also specifies a priority.

Specify the component to which the rule is to be applied.

Enter a description of the rule.

Tab Requirement:

As the requirement, enter the appropriate rule number for the product that should be used.
