Restriction on the reassignment of delegated tasks

Daniel

Hello,
is there a way to ensure that a task cannot be reassigned to the user if the user has delegated it or released it for other users?

The use case is as follows: A user takes the task (parks it) and releases it again (resets it). Or he delegates it to another user. Now it needs to be ensured that the task can no longer be assigned back to the original user.

Many thanks in advance.

Hi Daniel
I think best option is to manually filter the allowed delegation targets. Please check documentation link below.

Best regards,

Hi Timo Rupp
thank you very much, but how can I make sure, that this is triggered/updated everytime a user delegates the task?

Many thanks in advance.

Hi Daniel
Sorry, maybe I misunderstood your requirement. I'm not clear about the business case where this kind of logic is needed.

I don't have the final solution, but maybe a hint where you can have a look at...

Implement sub-process to customize list of delegation targets (as mentioned above)
In the sub-process, use API ivy.wf.findWorkflowEvents to find task reset and task delegation events and the users who executed it. Then you can remove these users from the list.

Maybe other users here can provide more detailed information.

Hi Timo Rupp
no problem, thanks for the hint. Now I know that I can use the API ivy.wf.findWorkflowEvents to get to the corresponding user for each delegation!

I have one remaining question: Let's say for simplification I want some script (e.g. the logging of "Hello World") to be executed every time the task is delegated. Where would I have to place this script or how could I make sure that it is executed every time a delegation is made?

You can write your very custom workflow event listener and execute code when they are fired.
As an example you can look at this teams-notification distributor, which handles task changes and sends microsoft-teams message accordingly.
