Making Records Read-Only According to a Field Value

The BC Read Only Field user property specifies the business component field that determines whether a record is read-only. If the value that this field contains is TRUE, then the current record is read-only.

If you set the Admin Mode Flag property to TRUE, then this setting overrides the BC Read Only Field user property. For information, see Allowing Administrators to Modify Records.
