An ATC exemption deactivates an ATC finding or set of findings for a set amount of time.

A developer may request an exemption if an ATC finding pertains to a problem that is a false positive or currently cannot be repaired or should not be repaired. If the exemption is approved by the quality manager, then the ATC finding is marked as inactive, and the ATC generates no new findings for the underlying problem.

The minimum scope of an exemption is for all instances of a particular check message in a single ABAP include or other type of repository object. Developers and quality managers should be aware that exemptions are not user-specific. That is, an exemption for a check message or entire check in code on which several developers are working masks findings for all of the developers, not just for the developer who requested the exemption.

Typically, a developer requests an exemption against the current active ATC result. In central quality checking, such a request is usually made from a satellite development system and is propagated to the central system for approval. The ATC saves exemptions; developers do not have to apply repeatedly for an exemption unless the exemption's validity elapses.
