BI 7.0 transports.

How exactly transports work in BI 7.0.

I have transported data sources in ECC - QA and replicated in BI-QA

Now how do I transport rest of object and in what sequence. I want to collect all in one request.

Do I need to transport data sources from BI Dev to BI QA...

What should be the sequence of transport, if I select in separate request.

Thanks
