XPath constraint entity read/write

Dear all, A question about how to link set up an XPath constraint. The following is the story: In the figure above the enitity is shown, and both flows go to the account entity in the project subgroup. Now, I wanted to make a page with an overview of the employees, which can only be accessed by the userrole ‘manager’ (which in fact is the link “Department_head”). How can I set up a page, such that the manager can only see the employees with the same department code, and not all the other employees? Thank you all in advance!

Retrieve the Account. Your xpath should look like this:

[Administration.Account_Department/ModuleName.Department/ModuleName.Department_Head = $CurrentAccount]

If used on a page you need to use the token for the CurrentUser.
