Hide sales information from employee

I believe it can be done but I am not sure how to do it.
I want to use ERPNext for employee to apply for leave.
However, I tried to login with their user account, I can see the Sales Information, The Sales Chart with monthly sales amount information.

How do I configure the the permission (Role) etc to archive that ?


Please check the permissions for that user account.
When you go to the roles of the user, you can click on each role to see its doc permissions.
If you just want to use it for leave purposes, maybe employee with employee account (link the erpnext user to the employee document) should be enough.
