It’s time for us to get out of our Development 
(DEV) system and into the Quality Assurance System (QAS) so that we can start testing the solution we are building. The truck icon is still there, same as it had been since I started working in earnest in SAP in 1995.
The idea is to ‘package’ up a packet of configuration table entries, or program code, and import it into the Quality System. No one is allowed to make changes directly in the Quality System. That way, if something gets broken in there, the offending configuration change or code change can be reversed out.
