How do I choose who to distribute the tasks to? in sap

A work item is assigned to one or more users. Whoever reserves or executes the task first wins and the work item vanishes from the other users' inboxes. This eliminates the need to assign the user to one single user. I.e. No need for complicated algorithms to determine which single user will receive the work item and no need to worry about what will happen when one user is ill for the week (also taken care of by sophisticated substitution mechanisms which can be linked to the SAP organizational model).

Tasks can be assigned to an organizational unit but the strength of the workflow system is to enable business rules which select users according to the data being processed. For example, you might have one group of users associated with one quality notification type. The workflow can be configured to query the QM module directly to determine the users. You can define fallbacks using the default role associated with a task and allow agents to be specified on the fly by a supervisor.

Tasks can be assigned to office distribution lists which is useful when you want your users to subscribe or unsubscribe to a particular task. A typical use of this would be where you have a work rote or want to reduce user maintenance to an absolute minimum. The users subscribe or unsubscribe by joining or leaving an office distribution list (one mouse click).
