Hello,
I'm hoping someone can help, I am very confused :-(!
We are currently running on Dynamics 365 Sales Professional license. By default we just have one parent business unit, however, we want to create a separate child business unit for another organisation working within our business.
The child business unit has been created, but I do not know how to access it within our Dynamics CRM. I have tried to access the environment via my user record.
When I try to add the environment as a team, I receive this error message;

I also tried to access the environment by changing the business unit within the 'Organization Information' box on my user, but received this message;

I basically want to be able to access a separate area within Dynamics which contains its own separate account/contact/opportunity records. I was hoping a child business unit could provide this for me.
I am also system administrator so should have full access to the system.
Thank you!
