RE: Cost of security roles, duties and permissions
I found the official licencing "guide" to be incomprehensible.
AFAIK we're only going to be using Finance and Operations plus Field Service.
My current understanding is that roles come with different license levels:
* SCM and Finance are two most expensive levels in the apps "Operations" and "Finance" respectively which just happend to be bundled into "Dynamics 365 Finance and Operations" so if you need both roles you pay twice.
* Operations equals "most expensive license in EVERY app you're using". So in our case for "Finance", for "Operations" and for "Field Service"
* Team Member is the cheapest and counts across all apps
* Activity is the middle ground and counts across all apps
But any custom role seems to automatically escalate to "Operations".
I would ask "is this correct?" but perhaps "how incorrect is this?" would be better... :-)
