stability study

Hi there

I have 2 requirements from my client:

1. For the first 3 process orders of a product a samle must be identified, placed at Quality stock and tested. If tested ok the sample must go back to unrestricted stock or scrapped. After the

2. Some products, which are produced very seldom (fx. 1 time each year), must be identified, placed at Quality stock and tested always as test is needed every time due to the seldom production.

I have looked into the Stability Study - SAP Help Portal, but I'm in doubt if this is the correct and most simple setup for the above business requirements

My client have already QM and EWM implemented.

thank you very much in advance for your help
