Dynamic Modification of the Inspection Scope (SAP Library - Dynamic Modification of the Inspection Scope)

Dynamic Modification of the Inspection Scope

Purpose

You can determine the sample size for an inspection in the R/3 System in different ways. For example, you can use the data from past inspection valuations to calculate the current inspection scope. To be able to react flexibly to this data, you can dynamically modify the inspection scope. This can be achieved using sampling procedures and dynamic modification rules.

Implementation Considerations

With respect to inspection characteristics and sample sizes, dynamic modification allows you to control the inspection scope for a series of inspection lots such that you will be able to achieve a predefined quality goal with a high degree of certainty. You can use the R/3 System to dynamically modify the inspection scope at different levels (for example, at the inspection lot level, characteristic level and inspection type level).

Features

At a specified point in time (for example, during lot creation or after the usage decision is made), the R/3 System determines the inspection stage(s) for the next inspection lot based on the predefined dynamic modification rule(s) and writes it to the data record as a quality level.

Depending on the level at which dynamic modification occurs, the system determines the next inspection stage for each characteristic in a task list to which a dynamic modification rule is assigned (dynamic modification at characteristic level), for all characteristics in a task list (dynamic modification at lot level) or for a specific inspection type independent of the task list used (dynamic modification at inspection type level). For dynamic modification at lot level, you define dynamic modification in the task list header. For dynamic modification at inspection type level, you define it in the inspection setup of the material master for the inspection type.

Note

It can be useful to use dynamic modification at inspection type level, if you want to use the same task list for several inspection types when you inspect with a task list. It is also useful, if you want to change from inspecting without a task list to with a task list without losing the current quality level.

You always maintain the quality level for the material and plant. This is dependent on the defined dynamic modification level for the inspection type, task list or characteristics for the task list. You can also define other dynamic modification criteria to maintain the quality level, for example, during goods receipt inspections by vendor and/or manufacturer, or for goods issue inspections by customers.
Depending on the dynamic modification level you have chosen, the dynamic modification valuation controls the following:

For the inspection characteristic - the stage change in the quality level for the inspection characteristic
For the inspection lot - the stage change for all characteristics in the quality level for the task list or the inspection type

The R/3 System determines the current inspection stage from the quality level in order to calculate the inspection scope and defines the inspection specifications accordingly in the inspection instruction.

A stage change can cause a reduction or increase (tightening) in the inspection scope.

As a rule the quality level is only updated on the basis of the dynamic modification valuation after the usage decision has been made for an inspection lot ( Dynamic Modification with the Usage Decision). However, you can also update the quality level at lot creation ( Dynamic Modification at Lot Creation). In this case, acceptance decisions are made for an outstanding inspection lot or outstanding inspection characteristics.

Note

Dynamic modification at lot creation is useful, if several new inspection lots can be created, before you have completed the inspection of the first inspection lot.

The conditions for a stage change are defined for each inspection stage in the dynamic modification rule. You can vary the sample size between a predefined inspection scope (for example, 100%) and a skip using the inspection stages. The inspection severity can change between a normal, reduced, and tightened inspection.

Note

A skip means that a certain number of deliveries, lots, or characteristics are not inspected.

During lot creation, the R/3 System reads the current inspection stage(s) for the quality level and uses this for sample determination.
