Process Critical Defect (QM-QN-NM) 
During a quality inspection, an inspector can record defects for the inspected goods in the inspection lot. The inspector records the defects with the help of catalogs and code groups. When you initially maintain the group codes for catalog type 9 (defect types) while setting up the Defects Recording component, you can assign a unique defect class to each defect type. The defect classes allow you to valuate the defects on the basis of their seriousness and their consequences. The following defect classes are recognized and used internationally:
Critical defect
Major defect
Minor defect
In the Customizing for Catalogs ( Define defect classes ), your system administrator can set various indicators for each defect class. One of these indicators can be used to trigger a workflow task. If an inspector records a critical defect for which the Workflow link indicator has been set in the defect class, the system trigger this workflow when the defect record is saved.
SAP Business Workflow
If the appropriate settings have been made in the system, the SAP Business Workflow automatically sends a work item to the integrated inbox of the authorized person(s), informing them that a critical defect has been recorded and that the defect needs to be processed. The authorized person(s) can process the work item directly from the inbox.
