Need to update Change Order EFF with Business Unit Assigned to Change Requester, 'Manage Users' → 'Business Unit'.

Trying to achieve it using 'Default Type' SQL in the EFF setup. In the Product Documentation, found that we can use #{PARAMETER.<PARAMETER_NAME>} in the WHERE clause.

Help me with 'PARAMETER_NAME' for Change Requester. Tried passing RequestorId and AssigneeId, getting error as invalid value.
