External Mapping for data mashup
Hi,
I am looking for a functionality in Power BI where I can externally map the multiple attributes to staging table attributes. There are multiple data sources with different structure and attribute names that needs to be added in one table. One way to do that is SSIS and connect the staging table to PowerBI directly. Is there any other way to map attributes in PowerBI directly ?
varunaggarwal30,
You can use DAX to create a new table, there is an example for your reference.NewTable = UNION(SELECTCOLUMNS(Stage,"col1",Stage[Column1],"col2",Stage[Column2],"col3",Stage[Column3]),SELECTCOLUMNS(sheet1,"col1",sheet1[Alias],"col2",sheet1[Column3],"col3",sheet1[id]),SELECTCOLUMNS(Report,"col1",Report[name],"col2",Report[Column10],"col3",Report[column1]))

Lydia

LydiaAnonymous Thanks!!!. I guess it should work..
Anonymous,
Is there any way we can have different column numbers and can add new columns from different sources. I tried add column option but it says union should have sam column
For Workaround I gave same columns in the all tables and kept them empty for non source table. Is there any cleaner way to do this?
