Creating a work package without an FWP

It is only necessary to create FWPs under a work package if you want to capture the resource estimates for the work package. The work package itself contains enough information to create a task. It contains the span time and predecessor-successor link. You can create and execute the tasks for work packages even if they do not have an FWP or resource estimates defined. The system uses the span time as the task duration and the predecessor-successor link as a constraint in the schedule. If there is no FWP under a work package, you can directly attach the deliverables to the work packages.
