Quick Base automation not working

An alternate approach could be to set up a saved table to table import of the table into itself based on Record ID# matching itself and some field(s) with the new value being mapped into the target fields(s) to update.  Have the Automation run this import for qualifying records.

Then rather than Quick Base seeing this as 1000+ individual record edits it will see it as just 1 import which is super fast to run, even if there are way more than 1,000 records to be updated.
