With the "Regulatory Establishment" field found in several places throughout HR...if you right-click on that field and select "View Details"...you will get the following error message:
Message (10:49:49 am)
Unable to View details, no form exists for table 'HcmEEOEstablishment'.I
The form DOES exist. The link to it is a BUG. (Microsoft knows about it). If you need to add a value into the system into that table, go to: Human resources > Setup > Workers > Regulatory Establishments
