Hi. I want to find in a FGDB (Esri) if some value are null or empty ( 2 filters) for a lot of table and feature class. Also i want to know if some field have different value from list of value. Thank you everyone !

@hugues​ Your first step would be to setup your File Geodb as a dynamic reader so all the feature classes are read with the same feature type. Have a look at this tutorial on how to get started with that.

Then TestFilter can be used to test for your <null> or <empty> fields. For the domain lookup, the DatabaseJoiner can be used to check against a list of values in a spreadsheet.
