A BPMN 2.0 Activity represents work that is performed within a Process. An Activity can be modeled as a:

  • Sub-Process - a compound Activity that is defined as a flow of other BPMN 2.0 elements or
  • Task - an atomic Activity that cannot be broken down into a smaller unit

Activities - both Tasks and Sub-Processes - can also, optionally, act as Looping constructs. The OMG BPMN 2.0 Specification defines two types of Looping construct:

  • Standard Loop (while or until)
  • Multi-Instance Loop (for each)

         -  Manual
         -  Receive
         -  Script
         -  Send
         -  Service
         -  User

Details Tab

Depending on the selected Task Type, the 'Details' tab changes:

Receive / Send / Service Task Type

  • Pool Package - Select the Package that represents one of the involved Participants
  • Operation - Select an Operation from the list of operation(s) in the selected Pool Package


(Optional) Select one or more Assignment elements created in the SupportingElements Package in this tab.

Assignment Create BPEL 2.0 Model Structure

Loop Details

(Optional) Activities can be repeated sequentially, in a looped circuit. Specify the Activity looping details in this tab.

  • Loop Type - Select 'Standard' for creating a 'while' or 'until' loop, or 'MultiInstance' for creating a 'for each' loop
  • Evaluate condition at the beginning of loop - Check this option to create a 'while' Standard loop; defaults to unselected for an 'until' loop
  • Loop Condition - Enter a Boolean condition for a Standard loop or a numeric condition for a MultiInstance loop
  • Loop Maximum - (Optional) Specify the maximum value for the loop evaluation for a Standard loop
  • Loop Ordering - For a MultiInstanceLoop Type select 'Parallel' for generating instances in parallel, or 'Sequential for generating instances in sequence
