Constraints in the Refreshed Web Interface
Constraints are applicable to fields in the Refreshed Web Interface. If a constraint is violated during edit or create operations, an appropriate error message is displayed. For example, if a constraint has been created to restrict the value of a field within a range, an error message is displayed if a value is specified outside the range. For more information on constraints, see the topic. Managing Constraints.
Key Considerations
When constraints are applied:
Some fields can become mandatory due to change in other fields.
All mandatory fields and tabs that contain mandatory fields are indicated with a red asterisk during edit operations.
Fields become editable or non-editable.
Filtered values are displayed in lists.
The Edit option for the item is disabled if an item is not editable due to some of the following reasons:
Your group is not authorized to edit items in the current state or any target state.
Your group is not authorized to modify mandatory fields that are not specified.
The item you are editing is currently in an end state.
The item editability rule set for the type is not met.
For further assistance, contact your administrator.
Type-based IBPL constraints that are designed to restrict allowed values on IBPL fields will be available in a future release of Windchill RV&S.
Type-based rule constraints set up for comparing two IBPL fields will be available in a future release of Windchill RV&S.
It is recommended to restart the Administration client to ensure that constraints get applied to fields after making changes.
After performing an Undo operation, the original constraints set on the field are applicable, whereas after a Redo operation, the most recent constraints set on the field are applicable.
