Get Source Query Name for each Record of Merged Query
Hi @Syndicate_Admin ,
Apologies for the confusion, the example I gave is just a visualization of what I want to achieve because I need it to be dynamic. My merged table consists of multiple left outer merges and I need to label each record which query matches the record in a Source column.
Hi kbl_22
Currently Power Query doesn't have a direct funtion to fill a column with its query name. You may vote this idea: A PowerQuery (M) function that returns the name of currently executing query
As you will left outer merge multiple queries, you will find that if there is any match record, the merged table value has rows. And the merged table value is empty when there is no match.
Based on above, you can add a custom column to have the table name based on the merged table value's row count. You need to perform this step manually after every merging.
if Table.RowCount([Table2]) > 0 then "Table2" else "Table1"
If this doesn't help, you may consider using the environment keywords #shared or #sections. But this may not be used easily and cannot work in the Power BI Service. You may refer to below links to read more:
