Factors That Influence Updating the Information Structures: Quality Management Information System 
In addition to the type of updating (immediate or delayed) and the period unit in which the values are cumulated, there are other options for filtering and varying the updating of data from the inspection processes.
Inspection Processing
Classification of Quality Scores
Inspection lots are valuated according to the quality score and the usage decision. Generally, an analysis of quality scores over a specific period is based on classed values. For this reason you can reduce classed quality scores.
You can define quality score classes that meet your specific requirements in Customizing for the Quality Management system. You can define up to five quality score classes.
Assigning Quality Score Classes to an Information Structure
In Customizing for the Quality Management system, you can then assign the quality score classes that you have defined (see previous topic) to the individual information structures used in the QMIS.
Assigning an Update Group to an Inspection Lot Origin
During inspection processing, you can use the Inspection Lot Origin to distinguish between the inspection lots. The inspection lot origin helps you to determine whether an inspection lot is from production or goods receipt.
Since the inspection lot origin works in conjunction with various key figures, the inspection lot origin must be integrated in updating control. You can do this by the assigning an update group to the inspection lot origin. If no assignment is made, no data is updated to the QMIS for the inspection lot origin.
You can assign an update group to an inspection lot origin in Customizing for Quality Management. In the standard SAP System, the appropriate update groups are already assigned to all the inspection lot origins in question.
Notification Processing
In notification processing, there are different of notification types. The notification type helps you to differentiate between a notification from defects recording or a notification from the customer.
Assigning an Update Group to a Type of Notification
You can assign an update group to a notification type in the Customizing for the Quality Management Information System. In the standard SAP System, the appropriate update groups are already assigned to all the notification types in question.
Update Group
The update group determines which information structures will be updated. The following standard update groups are available:
For example: if you have assigned the update group 20 to an inspection lot origin, the data from the inspection lot and the usage decision will be aggregated to the information structure for the vendor analysis.
