Multi Instance & Variable Aggregation | How-To | Flowable

In a process you can have multiple activities in parallel. One possibility to do that, is a multi instance activity behavior on tasks. In this video this will be done for a review, and the review data itself will be collected with multi instance variable aggregation and stored on the process level for all reviews. As conclusion, a common review decision will be generated and the individual comments will be displayed on a result task.
