Collaboration tasks enable adhoc, user defined processes. They be started from scratch, or they can be started from an existing task. If you are using universal worklist to access your business workflow work items, your user may want to start a collaboration task. When they do this, the execution of the work item is disabled until the collaboration task is completed or cancelled. In this first image I have an work item in my UWL about a material. In the bottom right of my window, I have the ‘You can also’ section. From here I select to ‘Create Ad-Hoc Request’. At this point I create my collaboration task and submit the task. Once this task is started, I cannot execute my work item until the collaboration task is completed or cancelled. This is very helpful, because I can easily see which work items have collaboration tasks, I can view the sub-process the collaboration task created, and I can ensure I wait for the process to complete before executing my work item. So, get on SAP NetWeaver 04, give this a try, and let me know what you think!
