 Control Parameters for RPM Products

Use

You can improve system performance by using this function to enter additional control parameters for the planning for every RPM product.

Note Note

If you plan material variants, you can only enter the control parameters for the higher-level configurable material. The material variants “inherit” the settings of the configurable material.

End of the note.

Prerequisites

In the product master for the final product that you want to plan using the RPM, in the Explode task list field, you have entered 4 for Matrix explosion of iPPE.

Features

Structure of the Maintenance Screen

The maintenance screen is split into a tree structure and into the detailed data that you can maintain for every location product depending on the planning version.

In the tree structure, the system lists all the products that are included in planning with the matrix. You can expand every product and the system then lists all the locations you have created for the product. For every location, you can display the planning versions you have created using the function Copy Planning Version . DEFAULT is displayed as the first planning version. For this planning version, you can enter the standard settings you want to use in the active planning version. You can choose your own settings for the other planning versions in the tree structure. You can maintain the control parameters for a planning version by double-clicking the planning version.

Defining the Control Parameters

In the detailed data, you can define the following settings for every location product in every planning version:

  • Creating an activity matrix

    When you set the indicator Create Activity Matrix for a product, the system creates an activity matrix during planning, in addition to the characteristic value matrix and the component variant matrix. For more information, see Determination of Activities with the Activity Matrix

  • Creation of sub-matrices

    In the No. of Sub-Matrices field, you can define into how many sub-matrices a planning matrix is to be divided. The matrix is divided up horizontally. During the planning run, the system generates the number of sub-matrices that you have defined instead of one large matrix.

    You divide into sub-matrices when a product consists of a large number of components, which means that the entire planning matrix consists of a large number of rows. Approximately 64,000 rows are technically possible. You can accelerate the planning run by dividing a large matrix into several small sub-matrices, and by using parallel processing for the planning run. For more information, see Parallel Processing During the Planning Matrix Run .

    In order for the system to generate sub-matrices during the planning run, you must enter the following data in the Global Settings : Parallel Processing field: Create sub-matrices even without parallel processing.

  • Checks for selecting multiple and required components

    In the Check Multiple Sel. and Check Required Comp. fields, you can state that the planning run is to check whether the multiple selection and required component selection conditions at the component variants could be adhered to at explosion for iPPE. When these selection conditions could not be adhered to, explosion errors are displayed in the matrix display and the order evaluations.

  • Technical Settings

    • In the Progress Indicator field, you can define that information about the progress of planning is displayed in the status row during the planning run.

    • In the field Maximum Number of Orders per Matrix you can define how many orders should be included in a planning matrix. If there are more orders, the system creates additional matrices.

    • In the field Use RPM Time Series , you define whether the system should create RPM time series for the components that were determined from the planning matrix of the selected product. For more information, see Generation of RPM Time Series .
