Reduce the Number of Records Pouring In
Community ChampionWhat is the data source?
How did you implement the filter- writing a sql statement or using the dropdown from a column heading?
"We tried clicking the "Transform Data" button., as a possible solution. But, upon trying to fliter the data based upon say "date", we could no longer find any records associated with the general ledger account number we want to report on."
- you'll have to read up on Query Folding. ODBC data connections don't always fold (sending the query back to the data source). They sometimes download all data requested from the source and then apply any filter.
Other things to take into account: Power Query defaults to showing 1000 rows in a preview, so that might be why you don't see the data you expect. Or the SQL might be incorrect.
SQL ODBC data source.
Filter = dropdown from column heading.
I have never herd of Query Folding. What is it?

Hi Anonymous ,
For "Query Folding", please refer to these documents:
Query folding guidance in Power BI Desktop;
Power Query query folding.In addition, how about using parameter to filter your data before loading the data into Power Query?
