Filter and join multiple data sources in Paginated report Power BI

Question

I have two different data sources in my Paginated report. One comes from Power BI Service and the other from Microsoft SQL Server .

My use-case is that, I send some parameters to the paginated report and filter the results in Power BI Service data source. Based on the information I get from the Power BI Service data source, I need to filter a view in Microsoft SQL Server . In the end, the information from these two data sources should be joined and used in the paginated report ( eg, in Power BI Service data source I have some non-personal information which needs to be enriched/joined with sensitive information from Microsoft SQL Server ).

Please note that I am working with big data here therefore the select to the view in Microsoft SQL Server should be as restrictive as possible.

One solution that I found was that, if two data sources come from Microsoft SQL Server, I can use subreports in paginated report and send information in XML format from one data source to the other - where I parse and enrich that XML information. However, since Power BI Service data source can only be queried using DAX or MDX, I don't know how to solve this issue.

If you have any hints or solutions that worked for you, please let me know:).

Example of data:

• Microsoft SQL Server

ID	Name	Address	PersonalNr	MaritalStatus
1	Test	Vienna, Austria	12345678	Married
2	Test1	München, Germany	87654321	Single

• Power BI Service

ID	Product	Quantity	Price
1	ProductA	12	12
1	ProductB	5	50
2	ProductA	1	1

• Final results from joining

Name	Address	PersonalNr	MaritalStatus	Product	Quantity	Price
Test	Vienna, Austria	12345678	Married	ProductA	12	12
Test	Vienna, Austria	12345678	Married	ProductB	5	50
Test1	München, Germany	87654321	Single	ProductA	1	1

To "join" across separate datasets in a Paginated report you can use the Lookup function.
