Reports in my workspace using multiple data source how i create deployment pipeline for that

Anonymous deployment pipelines are used for staging.
What this means: you have one workspace for development, another workspace for production (if needed, you can have additional workspace for testing).
And then you publish everything to workspace for development. 
Once everything is fine, you deploy it to next stage (test or production).
So each time you make changes only on development workspace and then you do deploy to next stages.

Here is the question if you need deployment pipeline?
If you published reports targeting different data to your workspace, it is fine, just make sure you enter all needed credentials (and gateway if needed) and it will all work fine.

I think the goal is now just to schedule refresh of your semantic models and then your published reports will be fine.

If i misunderstood the question, please share more information.
