In SAP S/4HANA Quality Management, codes from different code groups within the same catalog type can be grouped together in selected sets. Watch the video to learn more why and when to use selected sets.
The following figure illustrates an example of selected sets as it was introduced in the video:

In this example, the Quality Planner defines multiple code groups and codes in catalog type 1 (Characteristic attributes for attributive inspections). The first code group includes possible surface states such as rough, clear, frosted, smooth, and scratched. The second code group includes colors like red, green, and white. The third code group contains valuation codes such as everything OK, okay with minor defects, okay with major defects, not OK with major defects, and so on.
To describe the surface of LED lights, codes from the code group valuation are not used. Only the codes clear, frosted, and scratched from the code group surface are relevant, while rough and smooth are not used. Similarly, the color code yellow is also not relevant. To group the relevant codes from multiple code groups, the Quality Planner defines a selected set. They group the relevant codes together by referring to the respective entries from multiple code groups within the same catalog. Later, when the Quality Planner defines a qualitative master inspection characteristic or an inspection characteristic in the plan, they assign the selected set to the characteristic. When recording inspection results, the Quality Technician selects values from that list.
Note
The Application Consultant defines in Customizing for each catalog type whether the creation of selected sets is allowed. However, for catalog type 1 (Characteristic attributes) and catalog type 3 (Usage decisions), selected sets are mandatory.
The following screenshot shows how the Quality Planner maintains a selected set in catalog type 1 (Characteristic attributes):

The Quality Planner begins by defining a selected set in the catalog and then releases it. In our example, the Quality Planner defines a selected set that contains packaging materials.
Note
In contrast to code group and codes, you define selected sets on the plant level.
The following screenshot shows how the Quality Planner adds codes to the selected set:

The Quality Planner adds existing codes to the selected set. In our case, the codes paper, plastic, wood-wool, and so on are available in the selected set. Each code of selected sets of catalog type 1 must be valuated. If the valuation is rejected, you must specify a defect class such as minor, major, or critical defect. Later, the Quality Planner assigns the selected set to a master inspection characteristic.
For example, in an inspection plan for goods receipt inspections of LED lamps, the packaging material of purchased LED lamps shall be inspected. By assigning the selected set shown in the example to the characteristic Packaging material, the Quality Technician can select from the list of possible packaging materials (for example paper, plastic, wood-wool, no packaging material, and so on). If the valuation method in the sampling procedure assigned to the inspection characteristic automatically valuates the characteristic according to the valuation of the selected code, the system automatically accepts or rejects the characteristic. If, for example, the lamps are wrapped in paper, the system accepts this characteristic. If, there is no packaging material, the system automatically rejects the characteristic.
In contrast to code group and codes, you define selected sets on the plant level. Since codes in selected sets of catalog type 1 are valuated, the same code can be valuated as accepted in plant A, while it is valuated as rejected in plant B.
To create a selected set, the Quality Planner uses the app Edit Selected Sets. They have the following options:
Manually add one or more codes from a code group to a selected set. For catalog type 1, the Quality Planner also assigns a valuation and, if required, a defect class to the code.
Using the fast-copy function, the Quality Planner copies an existing selected set to a new one. You can only copy the selected set or also deep-copy all codes (including valuation and defect class) the selected set contains. When you copy a selected set or a selected set code to the selected set that you are processing, the valuation and defect class (if available) are also copied. You can change the valuation and defect class.
