You can enter classes as items in BOMs for configurable materials. You use these classes to classify materials, for example, that are used in different variants of the material. This saves you having to enter a separate item in the BOM for each material. When you assign characteristic values during configuration, the class item is replaced by a material that is classified with the values you assigned. The class you enter as a class item must have a class type that is the class node indicator in customizing. You can set this indicator in class types for materials or documents. For materials, class type 200 is defined for use in material BOMs in the standard system. For documents, class type 201 is defined in the standard system. You can maintain the additional data screen in classes of these class types. On this screen, you set the indicator that lets you use the class in material BOMs, and you can enter the item category of the resulting material.

Learn about the impact of multiple selection flags in high and low-level configurations, and how it affects component replacement and configuration saving. Understand the importance of maintaining consistency in your configurations.<br><br># This description was auto-generated #

Required component, if this flag is set, it has no effect in low level configuration. It has an effect in high level configuration, only if the material BOM or configuration structure is exploded, in other words, not in sales, nor in the sales view, off the planned or production order scenario without material BOM explosion, nor in the order BOM scenario, you then see an inconsistency message, if the system finds no components to replace the class node. The configuration can only be saved, with a status other than released. Multiple selection, if this flag is not set, it has no effect in low level configuration. It has an effect in high level configuration, only if the BOM, or configuration structure is exploded, and if the scenario used is sales order, with manual changes allowed, or order BOM. You then see an inconsistency message, if the system finds more than one component, to replace the class node. The configuration can only be saved with a status other than released. In this case, the inconsistency on the results screen can be resolved by starting the search for classified objects in either sales order maintenance, i.e. for scenario sales order with manual changes allowed, or technical post-processing, i.e. for scenario order BOM. We recommend that you do not use the multiple selection flag. The flag would mean, that the situation described, would not generate an inconsistency, and you would be able to save the configuration with status released. The class node can still only be replaced, by one material component.

Class nodes are a tool from variant configuration. In variant configuration, we often have terribly large BOMs, BOMs with more than a thousand items. Class nodes help to make these BOMs smaller, more readable, and more efficient. Instead of a large number of BOM items, each with object dependencies, we have only one item in the BOM with this class and possibly without object dependencies. Let's look at such class nodes. These are classes of class type 200. For example, here in the Fiore Launchpad. Manage Classes. This is transaction CL02. Here the class type 200 for the class nodes. Class type 201 can be used as a class node for documents. We are simply looking for all classes of this class type. There are only three classes of class type 200. Let's start with the first class for colors. The class has only one characteristic. And only classes of class type Class Node have this last tab, Additional Data. What's on that tab? The class can be used in BOMs. The system determines a low-level code. Here 3 means that the class can exist in a product structure on a maximum of the third level. Liter as the base unit of measure. L for stock item. Organizational level has no meaning. No selection of required component means that it is not an error if the class node is not replaced by a material number. No selection of multiple selection means that it is an error if the class node is replaced by multiple material numbers. In which BOMs is this class node contained? The answer can be found here. Environment, Wear use list, Use in configurable bills of material. Execute.  Eight bills of material are found. For example, let's look at the BOM for this material. Let's go to a second session. SAP menu, logistics, production, master data, bills of material, material BOMs, display. This is transaction CS03, the material and plant of left, the BOM usage using the F4 help. Here or better on the class tab, we see two class nodes, the class from the left and a second class node. Let's look at the second class node. This is also the second entry here, the engines. The class has two characteristics, and the additional data tab looks almost the same as before, except here. A selection of required component means that it is an error if the class node is not replaced by a material number. Back to BOM, you can check directly here which Material Masters were classified with this class. Select the class and choose Environment, Objective class, 9 Material Masters. You can also view the Material Master directly from here. Select the Material and choose Environment. Material Master. For example, these two views. This is a normal Material Master that has no special features and no reference to variant configuration. And here, the material is classified as normal. Back into the other class. Select the class and choose. Environment. Object to class, 6 material masters, back. Finally, let's take a look at the effects in variant configuration. To do this, we go to another session. Here we start the simulation. This is the material configuration simulation and modeling app. This is transaction CU50. Our plant 1010 for BOM explosion. Our material number. The simulation is started by this first button. Here's color. It is unvalued. Directly above this is the first feature of the engine. Also all unvalued. Then what does the configured BOM look like? Here, the sixth button equals result. BOM application PP01. Both class nodes are included in the configured In practice, this would mean that there is no color and no motor. However, according to the setting in the class node of the engine, this is an error. This is why we see the red cross and the inconsistency message. Back to characteristics. Let's evaluate the three characteristics for the class nodes. Yellow color. Diesel engine. Engine performance is 30 kW. What is the configured BOM now? Here is the 6th button. Both class nodes are replaced in the configured BM. Yellow color with glossy. Diesel engine with 30 kW. This is what the result should look like and we will end this demonstration.
