Hi Srikant,
Not sure if you are still facing the issue or you have already got some solution.
As per my understanding, you are able to see the environment in RSA1 in BW but not in BOC web.
For this, I would suggest to ask someone with SAP_ALL access to login to BPC web and see if he/she can see the transported environment. If yes, then ask them to add your user ID as admin to this environment and then try with your ID and you should be able to see the environment.
