i read that DEV,QAS,PROD are 3 Servers in SAPLANDSCAPE .
DEV has clients like 100(development),200(unit test).
QAS has also clients 180 etc.
PROD has client : 200 .
As an ABAP developer i will login to the development server and login with 100 client and write the code . and do unit testing .
now i will transport developed object to the QAS server and they will test test regressively. ?
