restrict access to positions (legal employer)

Hi all,

We have thesituation that we want to restrict the access to positions based on legal employer.

We are working withArea of Responsibility that look like the following (responsibility scopesecured by legal employer):

However, when configuring the person security profile we do not find the correct setting torestrict the access. We tried different options but nothing has ben successfullso far.

What kind of options do we have? How can we secure that the Key User only see the right positions? Do you have any ideas or suggestions?

Thanks in advancefor your support!

Kind regards,

Jana
