Steps of Activating Standard Data Sources

I need to know the steps required to activate standard data sources

As I know that first I need to activate data source in ECC Dev then transfer to QA then Production

And what about LIS Data Sources that need steps like transfer data to set up table ( Do I need to perform this in ECC production or first in Dev then transfer to QA then Prod ?)

And After replicating data sources in BW Dev and perform the required data flow from ECC Production. what is the steps to transfer the object from BW Dev to BW Production? Do I need to repeat my work in BW Dev?
