2 distinct data sources in one query
question
power query used to get data from 2 distinct sources
1 is a query that requires and is on prem gateway(MYSQL)
2 other is a query from non prem gateway- dataverse crm
no issue with query no issue with initial publish to power bi service
when refreshing it is indicating yes the deteverse source must also be placed on the on prem gateway since independently it does not need it but if included in query where other data source is on prem data source then yes it too must be on prem for refresh as it fetches data
Sound correct? i need to manually add that data source to the on prem gateway also in this instance?

Do not merge on-prem and cloud data sources in Power Query. As you have experienced, this will result in the cloud data source requiring a gateway, forever, even after you have removed the on-prem data source.
Don't do it. Leave these data sources separate in Power Query and join them in the Power BI data model.
If you insist on doing it anyway, convert your on-prem data source to a cloud data source (via dataflow or semantic model) before the merge.
what a good solution thanks for this insight big help
ok so instead first use power query to get on prem required mysql data source and once i keep only the columns i want and i add my dax codes then save it . to power bi service right?
2then in paralell use separate power query with only dataverse data source (no gateway needed) and again establish data and publish to power bi service
3 then you are saying use data model instead? meaning within power query click the data model to do relationships between two query right? but wont i first need to have obtained the data source that is on prem into the query anyway? not clear how to do the data model you reference or what the steps are-can you send general steps please?
Create two queries in Power Query, one for your on-Prem MySQL and one for your Dataverse.
Load both queries into Power BI
Join the tables in the data model
ok so step 1 power bi desktop step 2 get on prem data source 1- step transform and do steps in power query like normal to edit data etc step 4 save in power query and apply to desktop power step 5 do same for non prom data source in its onw power query separate- step 6 then open one of the 2 power bi desktop and from there join the table in the data model step 7 then publish to power bi service step 8 service should then allow refresh without requiring both to be on prem gateway for refresh ? ok let me try this thanks
This is all done in the same Power BI Desktop PBIX.
