SOURCEROWNUMBER function generates null values consistently
The SOURCEROWNUMBER function returns the row number of the row as it appears in the original dataset. After some operations, such as unions, joins, and aggregations, this row information is no longer available.
Previously, the results were confusing. When source row information was not available, the function was simply not available for use.
Now, the behavior of the SOURCEROWNUMBER function is more consistent:
- If the source row information is available, it is returned.
- If it is not available:
- The function can still be used.
- The function returns null values in all cases.

Welcome to the inaugural release of the cloud version Trifacta® Wrangler! This release represents the migration of the prior version of Wrangler for the desktop to the cloud, where you can take advantage of more storage and faster processing.
NOTE: As of this release, the desktop version of Trifacta Wrangler is no longer updated. You can continue to use the product for a period of time. However, at some point in the future, this product will be terminated and no longer accessible.
