Define Defect Classes
In this step, you define the defect classes that are used to valuate the defects qualitatively on the basis of the defect consequences.
These defect classes are used in the following places or for the following purposes:
- In the selected sets for catalog 1 (characteristic attributes)
- In catalog 9 (defect types)
- For the valuation of characteristic inspection results
For each defect class, you can specify:
- A quality score
- Whether a characteristic attribute in catalog 1 with this defect class can be valuated as acceptable
- Whether the following can be activated:
Activities
Define the required defect classes and their properties.
If you want to trigger automatic follow-up actions that are dependent on the defect class, refer to the following section of the Implementation Guide:
- Environment -> Central Functions ->
Workflow
Additional Information
You need the quality score default values for
each defect class if you want to use a corresponding valuation procedure for
the
quality score of inspection lots.
In the
Settings at Plant Level , define a default value for the defect
class.
In the master data, the defect classes are used in the following catalogs:
- Catalog 1: characteristic attributes, selected sets
- Catalog 9: defect types
The following defect classes are effective during results recording:
- If a defect type is specified in the inspection plan characteristic, the system selects the defect class associated with the defect code. The defect codes are defined in catalog 9.
- If a defect type is not specified in the inspection plan characteristic, the system proposes a defect class. It selects the default value as follows:
- At the respective lowest level (this is the
level of single values, classes, summarized characteristics or samples,
depending on the recording from), the default value is selected from the table
of default values at the plant level.
If you valuate qualitative characteristics on the basis of an attribute code, the system uses the defect class stored in the selected set for catalog 1.
- On the more global levels - that is, when you valuate characteristics or samples - the system applies the worst-case principle; it searches for the defect class in the respective lower levels with the lowest quality score and proposes this class as a default value.
- During results recording, the user can change, retain or automatically copy the default values for the defect classes.
