To quickly create tasks for implementing requirements (Enhancements) for a whole document, you can use the "+ Enhancements" bulk operation, located at the top of the document, next to the "Actions" button.
Requirement documents are usually composed so that not every section is, in substance, a requirement that must be implemented. For example, only use cases may be implemented, while the documents also contain general sections such as "Introduction", "Terminology", and so on. ALM recognizes the requirements for which an assignment must be created based on the requirement type. In the requirement type reference list, you can set the "Implementation required" option for the requirements you need. For requirements marked with this type, the system offers to create Enhancements, and also lists them in bulk operations that create assignment tasks.
Sometimes the requirements that must be implemented in the next product version are located in different documents. This is normal practice for maintenance: we implement, in portions, what is needed. In this situation you can use the bulk operation that creates Enhancements from the requirements registry, filtered as needed — by state, readiness, or other selection criteria.
