When assigning a work item in Azure DevOps, I want to validate that the "Assigned to" area is set to a member of the team corresponding to the Area Path or prohibit users from assigning a work item to someone who is not in the corresponding Area Path assigned teams.
For instance, if I have two groups, Group A and Group B, and each has their respective Area Paths (e.g., "Project\GroupA" and "Project\GroupB"), I want to set a rule so that only Group A members can be assigned to tasks within "Project\GroupA" and not in "Project\GroupB", and vice versa for Group B members.
I don't want to prohibit either groups from viewing and editing the work item otherwise from the other groups, just the "Assigned to" value.
Is there a simple way to do this?
I have tried to set up rules for the work item types in the Project Settings > Boards > Process > 'Work item type' > Rules, and add new rule, but I am not able to find a condition or action that match my requirements.
I also tried looking into Project Settings > Boards > Team Configuration > Security. Here I have found the option to "Edit work items in this node" and deny this for the teams that I don't want to give this permission to (or deny this by default in the root project and then allow for the specific teams I do want to have this permission), but I don't really want to do this as this feels too restrictive, and I am only interested in validating that the "Assigned to" field is correctly set.
Update: I have submitted a feature request for this in the developer community of Microsoft. I am sharing the link here if anyone would like to vote for it: https://developercommunity.visualstudio.com/t/Validate-that-assignee-of-work-item-is-p/10698443
