Hi Abhishek
are you talking about one development XXX and 2 Production as common final target system
OR one development with XXX and other one YYY having target as AB1 and AB2 respectively?
In ChaRM RfC has the Target IBASE so all TR know whether their target is AB1 or AB2.
If this is not the case then can you share more details about logical component and all the systems which are in these logical component mapped in?
basically the Maintenance cycle controls all the TRs for any project so this will help to control transports going in sametime etc.
there are lot of good FAQ here ..hope you have checked it already
Change Request Management scenario: Usual questions and known errors
thanks
