Basic Data for Stability Studies

To be able to conduct stability studies, you need to define storage conditions and scheduling strategies as basic data during the implementation phase of your project. In preparing your system for the stability study, you must first identify which different storage conditions will be tested in your company and you must then define these storage conditions in Customizing for the Stability Study.

In addition, you must determine the different time bases and time intervals that you will need to conduct stability studies. You define these time bases and time intervals in the form of strategies with corresponding packages. Keep in mind that a strategy can contain a superset of all possible time intervals that may be needed. For example, you might define a strategy for a five year period which contains each single month as a package, even though you might only need a specific subset of packages for scheduling purposes in a given stability study.

This approach provides the following advantages:

It allows you to keep the number of strategies in your company down to a minimum.

You can schedule additional testing dates during the course of an ongoing study that were not planned at the beginning of the study. For example, you can schedule an additional test after 10 months, between the originally planned tests after nine and 12 months.
