Hi Carolina ! 

I think you’ll find very helpful elements in this article written by Samya. 

There are basically 2 steps: 

1. Create a Metric of data type Access Right by User and any relevant dimension for your access rights management
2. Apply this Access Rights Metric to your Application

Your Case

Here what you’ll do is create a new metric of type Access Right, with the dimensions User and Cost Center in the structure (Your Scope per User metric seems almost there )

That way, you’ll be able to manually assign Read and Write access for each User x Cost Center. Follow Samya article to apply those access rights to your Application.

If you want to assign Cost Centers with a formula (for example Admins can have access to all Cost Centers) you can use the formula bar with if statements (using the accessrights function). Something like this for example : IF(‘Users Roles’ = Role.”Admin”, accessrights(true,true),accessrights(false,false)). You can combine that with the override functionality to manually input with Cost Centers are authorized for Cost Center Managers.

I hope this helps and welcome to the wonderful world of AR !

@Nathan I followed your article, I got to do until the AR: Country x Dpto but I got stuck in this part of edit access rights rule. Where is it? I couldn’t find it.

Hi @Carolina Lee ,

You will find it in the Security settings page.  

The section you are looking for is Complement the roles with access right rules. 

You can see an overview of the page here.
