Change data source in Power BI service

[GOT2021]

Hello, I'm new to Power Bi service, so I'm having trouble doing some things (maybe not possible at the moment).

I have several Postgresql data sources, I have access to one (the dev one) locally and the other not (I use a data gateway for prod one).

What I'd like to do is, once my dashboards have been developed on dev data, publish them in the project and then in the prod project, but using the prod data source in the prod project.

The two data sources have the same table names with the same columns.

I'd simply like to be able to change the data source in Power BI service.

Thanks

Yes, Parameters is the right approach.  Did you use these parameters in your original connector?

Yes @lbendlin @abpgupta , I finally managed to solve the problem

1. I couldn't edit the parameter fields on the PowerBI Service side to put the prod url, so I had to do this : change Type Parameter to "Text" in Power Query

2. Once published, I still had the data from the dev database even though I'd modified the source, but I had to do this trick : reload the semantic

Everything's working fine now, but you may have some suggestions for improvement.

For string inputs, always use Text as type of data and avoid using "any". You can also create list of values as table and use as input in parameter to have control on string values.

I've seen this option in Power BI Desktop and I've added the two urls, but Power BI Service doesn't suggest the selection. I still have to enter the url and database name.

That's correct. The Power BI service doesn't care about choice fields. You have to provide the values.

It's perfect, thank you both for your feedback @lbendlin @abpgupta

In Power Query, you can define Parameter and input all databases name as input. All other queries should be changed to use this parameter to refer for Data source name/connection strings.  Once published to Service, it will be available to set on Semantic Model's settings.
