How add a group by option in my custom transformer? Example:FME_group_by_3

 

 

Another example might be if I put a Counter with local scope starting at 0 inside the custom transformer, then I would like to group by for instance _creation_instance - to get three features out all with _count = 0.

 

In the Custom transformer I see a setting Group by <not set> but I am not able to edit that one (there are no suggestions when opening it). I tried creating a parameter called fme_group_by but that did not work either. How can I do this?

Right click on the Group By: Parameter to create a parameter (this is named FME_PROCESS_GROUP_BY by default), then in your main workspace, in your custom transformer you should have an option to set the Group By parameter, e.g.

Capture
