It's really just for the pre-filling of the next input field for easier selection of the values. That's why SQL queries are used for in this example.

The problem with the finders/filters is more with the accuracy of the data. Without any preview/testing of the workflow, you are not sure, that the process will execute based on the filter. With the SQL queries, you already know, that this input is valid.

Is it possible to validate the filter/finder input prior to run the workflow with some return codes?

Thanks a lot, this helped me a lot.
