Creating sub-teams
Use these steps to create a sub-team. You can specify a sub-team for any team that has a team type of HRORGUNIT.
After creating a sub-team, ensure that its Team Hierarchy Type is set to HRORGUNIT. Sub-teams can only be assigned to parent teams with a Team Type of HRORGUNIT if both teams share the same hierarchy type.
Assigning a sub-team with a mismatched or undefined hierarchy type, such as None, triggers a validation error: Only teams of type HR Org Unit can have a subteam type.
