Access in TK'Blue can be granted either to all GBUs or to selected GBUs.
At Solvay, we decided that key users shall have access to their GBU only, except the ones with a global role.
The other transversal stakeholders (admins, service owner, sustainability leader...) may have access to all the GBUs
You need to filter by GBU first, then create the access you will apply to your previous selection
