Hi, we would like to know which business object is related to the Employment section from Person Management:

Our purpose is to edit the collective agreement section of an employee; in particular, we need to upload this contracts to employees and other users, but we didn't manage to find a Business Object related to the Employment page; we did find the BO named "Collective Agreement", but I think it's made for mass creation of Collective Agreement and not to assign them to a Person.
