A set in Jama contains items of the same type.
You may create multiple sets of the same type in a project. For example, it's common to have a set of Business Requirements and a set of Non-Functional Requirements that both share the Requirements item type.
Items that belong to sets of the same item type can move or be copied between sets. In the above example you could move a Business Requirement to a Non-Functional Requirement. However, items within a Use Case set that are a different item type cannot be copied or moved to the Business Requirement or Non-Functional Requirements set.
Note: Your Administrator can add, configure and customize the item types for a set in Jama.
Sets can be added and edited just like other items.
