User rights - Bypass traverse checking on Windows 2012R2

Hi,

We are using Windows Server 2012R2 for a file server.
We have installed the essentials windows server Dashboard on this.

On the local drive, we have shared some folders like "Data, administration, operation, finance,.."
On the "operation" folder, we have a subfolder... for exemple "abroad_operation".

For one of our users, we need to give permission to access "abroad_operation" but not to "operation".
For this moment, we are setting on "Operation" read access and then on "abroad_acces" read/write access.

If I set no access on "operation" and give full control on "Abroad_access", the user has no access to the folder...

Needs some help.

Thanks a lot in advance.
