The User Defined Fields tab is only displayed in situations where User Defined Fields have been created and positioned on the designated tab. This tab will then display all User Defined Fields in the sort order indicated in their setup, for each User Defined Field category.
When creating User Defined Fields, fields can be grouped together in different categories. Each category can display 50 user defined fields on the designated tab.
This tab can be disabled for individual users through settings in the Eralis Job User Authorizations.
