Figure 22: Allowed Relationships
The allowed relationships contain combinations of dynamic modification rules and sampling procedures with reference to a sampling scheme. Sampling procedures without a sampling scheme are not relevant for allowed relationships.
If you enter new entries for allowed relationships, the system checks whether corresponding entries (sampling plans) are available in the relevant sampling scheme for all inspection severities in the dynamic modification rule and for any available AQL value in the sampling procedure.
In a task list only combinations of dynamic modification rules and sampling procedures with a sampling scheme are allowed that are defined as allowed relationships in QM.

Exercise 3: Dynamic Modification Rule
Exercise Objectives
After completing this exercise, you will be able to:
• Create dynamic modification rules.
Business Example
You reduce the inspection scope using suitable dynamic modification rules so that you can reduce the expense of inspections as a result of improved quality. These can also allow for an inspection skip.
Task:
Dynamic modification
1. Creating a dynamic modification rule without a sampling scheme
You reduce the inspection scope using suitable dynamic modification rules, so that you can reduce your appraisal costs as a result of improved quality. Define dynamic modification rule A## for dynamic modification when you make the usage decision. A reset period is not needed for the quality level.
The initial inspection stage does not allow for an inspection without a sampling scheme. The second inspection stage should allow for a skip. At the next inspection stage, the inspection should be performed without a sampling scheme.
If no inspection lot is rejected after four inspections with the initial inspection stage, five inspection lots should be skipped. Then, there is another inspection.
If this inspection is OK, five more lots can be skipped.
A rejection at any stage of the dynamic modification rule takes you back to the beginning of the cycle. That means to the initial inspection stage.
This dynamic modification rule must not be added to the allowed relationships.
Make a note of the individual inspection stages:
I n t e r n a l U s e S A P P a r t n e r O n l y I n t e r n a l U s e S A P P a r t n e r O n l y
Make a note of the settings for the stage change:
OK Not OK
2. Creating a dynamic modification rule with a sampling scheme
Define another dynamic modification rule B## for dynamic modification when you make the usage decision. A reset period is not needed for the quality level.
The initial inspection stage allows for an inspection with the inspection severity Normal. The inspection severity Reduced should be used in the second inspection stage. The third stage of the dynamic modification rule should be a skip.
If no inspection lot was rejected after four inspections with the initial inspection stage, four more inspection lots should be inspected with the inspection severity Reduced. Then inspection lots should be skipped. The inspection lots should not be skipped for more than 100 days. After this period, four inspection lots should be inspected with the inspection severity Reduced.
A rejection at any stage of the dynamic modification rule takes you back to the beginning of the cycle. That means to the initial inspection stage.

Add this dynamic modification rule to the allowed relationships with your sampling procedure SP03-##.
Hint: The maximum number of skips is limited to 32,767 because of the nature of the database field. You must also enter the number of skips when entering a maximum skip duration in days.

If no inspection lot was rejected after four inspections with the initial inspection stage, four more inspection lots should be inspected with the inspection severity Reduced. Then inspection lots should be skipped. The inspection lots should not be skipped for more than 100 days.
