How to use Esri Geodatabase writer to fanout to multiple Feature Classes nested in multiple dynamically named/created Feature Datasets?

What are the names of the DWG files you are dealing with? Feature class names must begin with a letter and must only contain alphanumeric characters or underscores.

I've renamed the files to DrawingA, DrawingB etc. so I'm fairly sure it's not a naming convention issue... also the feature classes create fine using @Value, but when using @Value(fme_basename) in the feature dataset , it gives me the error that 'the table name is invalid. fme_basename is simply DrawingA, DrawingB etc.

@lxk​ It doesn't look like you can use an attribute for the Feature Dataset in the Esri Geodatabase (File Geodb) writer. But in the Esri Geodatabase (File Geodb Open API) writer you can use:

@Value(fme_basename)/@Value(Layer)

in the Feature Class or Table Name.

We'll try and get this changed in the Esri Geodatabase (File Geodb) writer.

@markatsafe - has this been resolved? I had upgraded to Workbench 2023 but it would no longer allow writing to a feature dataset inside a file geodatabase, even if I hand type the correct filename structure. I rolled back to 2022 so I can continue my work flow, but would like to know if this has been addressed since I have several scripts writing to feature datasets. Thanks.

A year later this is still not fixed?
