Defining Interface Design, Characteristic Grouping, and PMEVC

Objective

After completing this lesson, you will be able to define an interface design / a characteristic group, and work with PMEVC.

Interface Design

The following figure shows you the use of the interface design of LO-VC.

A software interface for LO-VC is displayed, highlighting profile-specific, user-independent features with tab pages, a summarize function, and push buttons. The interface includes a characteristic value assignment table.

Note

Please keep in mind the following: You can define 15 buttons and 10 tab pages, maximum.

The next figure shows you the settings available for the interface design.

The image outlines configuration requirements and definitions for LO-VC, highlighting the type of characteristic group with options like Tab, Sequence, Aggregate, and Printouts. It mentions values, interface design, and characteristic grouping inside the value assignment screen.

Interface Design for LO-VC

Authorization object, C_LOVC_DSG

Using the User Interface, you're able to add a pushbutton as characteristic grouping. If the name of the characteristics group starts with CUSTOMER_PUSHBUTTON_, the system works with a User-Exit (A user specific function in customer exit CEI00000).

Only Materials

Sequence: In sales (customer order and configuration simulation) or for engineering (order BOM and configuration simulation). If you do not set an indicator, the sequence is valid for both.

Print relevance in sales (order confirmation, delivery, billing) or purchasing (order). This function is integrated into the print function for sales and purchasing. If no characteristic group is maintained for the item to be printed, all characteristics with a value assigned are printed (including the hidden ones). If there's a characteristic group for the print output, then only the characteristics with values that are assigned to the group are printed in the sequence defined.

Interface Design / Characteristic Groups for AVC

A screenshot of an AVC interface design showing configuration profiles with characteristic groups and settings for dimensions such as length, breadth, and height. The image includes arrows highlighting interface sections and results for different operations such as string operations and equation systems.

When you work with AVC, you have to use characteristic groups instead of interface design of LO-VC. Watch the following video, which gives you an explanation.

How to Show Interface Design / Characteristic Groups of Materials

The following simulation shows you first the existing interface design and characteristic group of a material. In a second task, you create a new interface design and characteristic group for a different material.

Product Modeling Environment – PMEVC

Image shows screenshot with repetition and additions to Product Modeling Environment.

The Product Modeling Environment (PMEVC) is an alternative transaction as all other transactions are still valid.

You can create and change most of VC master data.

Some of maintenance transactions in PMEVC are better and more elegant as in other transactions.

PMEVC Maintenance

The following restrictions exist:

  • Master data such as material master, BOM, routings or classes cannot be created.

  • These master data cannot be changed in principle (that is with Exceptions for Assigning Object Dependencies and Overwriting Characteristics).

  • The PMEVC can only be used for configurable material masters and not for other configurable object types.

Create a Table Constraint Using a Wizard

You realize that only for some combinations of Type of Drive and Engine Performance material components exist. Therefore, you have to define a table constraint that defines possible combinations.

The next simulation shows you the creation of a table Constraint using a wizard in the PMEVC environment.
