After an employee transfers to another entity, does the HR of the old entity still have access to the profile of the transferred employee?

No, the old HR does not have access to the employee’s profile after the transfer to a new entity unless the HR person has the role of Global HR or Entity HR for the new entity. The reason for this is that the HR of the old entity should not see the evolution of the employee’s professional and personal data after the transfer due to confidentiality and data privacy. However, the HR of the old entity can still run reports that include data of the employee as of the last day in the old entity before the transfer.
