Use

The Restriction Hits view is an additional periodical chart in the product planning table, which appears in the selection tree, and can be accessed if you have set the profile Model Mix Production Planner . It shows the utilization of the lines, for which you have created certain Restrictions.

The restriction hits view allows the orders for selected restrictions to be displayed, which are “hit” by these restrictions. These are the orders, whose characteristic value assignment fulfills the object dependency, which is stored in the restriction as a characteristic value.

The order quantities cumulated using the periods (shift, day, week, month), are displayed in the Current Load row.

The minimum and maximum allowed quantities for the orders are displayed additionally in a separate row, which you have defined for the characteristic value in the restriction.

The system calculates the load as a percentage using both values. The utilization is displayed as a percentage in the row with the name of the restriction. If an overload (>100%) or an underutilization (<0%) occurs through the current load, these cells are displayed in red.

You have defined the restriction “a maximum of 50 air conditioning units per day” for line L1. The system now determines the vehicle orders for line 1, which require an air conditioning unit to be fitted.

The system determines, the number of orders for vehicles with air conditioning for one day and displays this (for example 100). As a maximum quantity of 50 vehicles with air conditioning is allowed, this causes an overload of 200% on line 1.

Integration

The restriction hits view allows a restriction specific evaluation of the results of the model mix planning and sequencing.

When displaying the restriction hits in the product planning table, differences can occur in the display between the minimum/ maximum allowed quantities and the data in the sequencing. These differences arise, as contrasting methods are used to round the calculation results:

In model mix planning, the maximum allowed quantities are rounded down as standard, as the quantities specified in a restriction are not allowed to be exceeded.

In the product planning table, however, the minimum/ maximum allowed quantities are calculated exactly, and displayed with a decimal place, should decimal places exist.

In order to avoid greater differences in the display of the minimum/ maximum allowed quantities, you should set the same periods in the product planning table, as you used in the Planning Basis , which you have specified in the procedure package for that particular planning horizon. If you have selected the setting “cumulate per day” in the planning basis, then you should also select the period “day” in the product planning table.

The contrasting calculation methods for rounding the calculation results, are highlighted in the following examples:

Prerequisites

You have created the restriction .

To ensure that the restriction hits chart is displayed in the navigation tree, you must have accessed the product planning table using the profile SAP_MMP production planner model mix . If you have used a different profile, then you can select the variant SAP_MMP from the user settings in the product planning table.

If this variant is not displayed, then you have to load the profile from Customizing, by selecting the Load profile from Customizing function key. The same dialog box is then displayed, as that which is displayed the first time that you accessed the product planning table ( Selection of the PPT initial view ) where you can choose profile SAP_MMP and save it as a user variant.

Activities

Initially, only the Product View: Quantities Graphic and the Production View: Periodic are displayed with the Production Planner Model Mix profile. Display the Restriction Hits chart , by pulling it using Drag and Drop into the upper area of the selection tree, or by clicking on it.

Select a restriction and choose the icon .

The master data for the restriction appears and you can display the characteristic value combinations (object dependencies) for the particular restriction type.

If you choose the icon, further user settings appear which are only valid for this chart.

If you have defined restrictions for alternative groups of lines, specify a reference calendar in the General group frame. Specify the reference calendar which you have entered in the procedure package. A link takes you to the maintenance for the planning calendar, in which you can also create a new calender.

The function that automatically updates the chart. When you do so, the icon appears in the application toolbar, which allows you to update the data manually.

Under Selection you can choose whether all restrictions are displayed for the selected lines, or a selection of up to ten restrictions, which you have defined in a visualization profile. See also: Visualization Profile in the Restriction Hits Chart .

In the Label group frame, you can define which objects are specified in the label row and in which sequence.

You can display the details by clicking on an entry in the row Current Utilization . A list is opened in this area with all orders which apply to the restrictions in the corresponding time interval.
