We currently use SOAP web services to feed our active employee list to Nexonia (our timesheet/expense reporting app). Only employees who have a custom entity field called "For Nexonia" checked on their employee record get synced. I'm trying to track down how that filtering is happening. I can't seem to find any obvious script or workflow. Any thoughts?

Maybe it's on the web services side, I would look at the SOAP Usage Log (Setup -> Integration -> Usage Log)

Thanks for your input. I had already checked there and didn't see anything obvious. I decided to go back to Nexonia and look at the integration on that side and I think I found it there. Not what I was hoping for. I want to try to filter another field that is coming over to Nexonia and I'm trying to figure out a way to do it. Back to the drawing board I guess! Thanks!
