I have a query regarding task assignments in IBM BPM. My understanding is that tasks can be assigned to groups, individual users or group of users.

Is there an API(JavaScript/REST) which tells us that the task is assigned to an individual user or if it is assigned to a group.

What is a good way to handle a scenario where if a task is assigned to a user, then any other user should not be able to claim the task as it is already assigned to an user(individual). If it is assigned to a group, then the user(individual) can claim the task to work on it.

Thank You,

Sathish Kumar

Hello Sathish,

Yes your understanding is correct a Task can be assigned to a group or to an individual user.

Yes there is, in Business Automantion Rest Api tester: https://host_name:port_number/bpmrest-ui

Process API and Task API (Here you can use Task Detail service it may hel your need).

Hope this can help.

Hello Sathish,

You mention a particular scenario, that I copied here:

What is a good way to handle a scenario where if a task is assigned to a user, then any other user should not be able to claim the task as it is already assigned to an user(individual). If it is assigned to a group, then the user(individual) can claim the task to work on it.

This is precisely what BAW provides. If a task is assigned to a user, then that task does not appear on the work lists of other users. If the task is assigned to a group, then it will appear on the work lists of all users in the group. Once a user in the group claims the task then it is automatically removed from the work list of the other users.
