Hi everyone!I’m learning about dynamic flows in FME and I’ve encountered two issues that I haven’t been able to resolve yet. I’m reading multiple .gpkg files from a folder, but in the output, all the data is saved in a single .gpkg file. I need FME to generate a separate output file for each .gpkg read. How can I set this up? When I insert the Attribute Manager and rename the attribute from acm_id to id, the values of that attribute (acm_id) turn null after the renaming, and the new attribute (id) does not appear in the final output file. Does anyone know how to prevent this from happening? Thanks in advance for any help or suggestions!
