Database refresh of source system and BW system connection again
We have recently implementing BW-DEV and BW-QAS systems and lot of developments are going on both systems for which source systems are R3-DEV and R3-QAS system. Now as quarterly task we are going to perform database refresh from R3-PRD to R3-QAS. So what are all factors i need to take care while making connectin again from BW-QAS to newly refreshed R3-QAS system.
Please note there is no BW-PRD system yet installed.
<b>Do i need to perform entire configuration again from R3 to BW QAS.</b>
again create all RFC's , what will happen to extraction scenarios developed by developers ?
Normally we should do refresh in parallel for R3 and BW systems ?
