In the project configuration, you can use both workflow and field rules to set limitations on fields. If you use both, the following behavior should be considered:
Workflow rules that are designed to restrict the value selection of a field cannot be undone using field rules. Restrictive workflow rules are therefore the stronger rules.
The following properties in the workflow in particular, cannot be overwritten by field rules:
not editable
required
value
Softer rules, for example "editable", can be restricted by field rules and set to "not editable". Enclosed is the complete list of field settings in the workflow that can be overwritten by field rules:
editable (=> not editable)
not required (=> required)
visible (=> not visible)
not visible (=> visible)
highlighted (=> not highlighted)
not highlighted (=> highlighted)
The visibility as well as the highlighting have no influence on whether a value can be set or not. It is a purely visual aid.
