What happens if I change a value in the field definition of a drop-down list in Rally?
Release : SAAS
The behavior reflected in changing a dropdown list value in Rally depends on whether the dropdown list type is a single select or a multi-select.
For single-select dropdown fields, changing the value in the field definition will have no effect on the work items that have this value set. This is because, for single select fields, the field is treated more like a pick-list and the actual text is stored with the work item, instead of a reference back to the value. It is necessary to manually update work items with the new value if you need them to reflect the change.
For multi-select dropdown fields, changing the value in the field definition will correspondingly update the value on the work items where that value is set.
