Hi Felix,
The SPAU Transaction should be perform after oder before we have activate the business functions?
SPAU should be performed after any patch application or Version upgrades. It has no relation with business functions activation.
What ist the best way to determinate the test scope for an integration Testing
Scope of any testing can be defined by the business scenarios implemented within customer environment. You should have business process master list based on which you can determine the integration testing scope
