Advocate IIMerge columns in Paginated report
Hello rnola16,
Thank you for reaching out to the Microsoft Fabric Forum Community.
To answer your question the Report Builder doesn’t support merging datasets like a SQL JOIN or Power BI relationships.You can use the Lookup() function to fetch values from other datasets, but that only works one-to-one (like a left join). If you have 10+ datasets, this means you'll need to:
- Use a master dataset that contains all distinct ID/Name keys (via UNION)
- Use Lookup() for each column you want to bring in from the respective dataset.
Alternatively, if you're able to, building a SQL View or Stored Procedure that handles the full outer join across your datasets will give you the cleanest and most scalable approach.

Thank you.
Advocate III can do this using UNION by combining all the queries, but there comes a point when I have like 10 different queries ( with different number of col in each) and merge on field to retrieve other col values in the tablix. Is report Builder equipped to merge columns on a field with muliple datsets ?
Appreciate your response Bmejia .
