Hello, I have a project where a default data source has been chosen. I want to be able to write to two data bases at the same time. Is this possible in ignition? It is only letting me push data into the selected default DB and not the other. I’m using the same script for writing to both data bases. Thanks!!

Yes, you just have to specify in the script call which database to write to at that point (by data source name).
