The Help documentation indicate that warehouse bins are available in 365. I do not see it. Has it been released? If not, why does the help documentation indicate that?
Help for Dynamics 365, Business edition reflects the full application scope, which will be generally available in Spring 2018. (This was announced with What's New for the November update.)
The reason is that the full application scope is available for preview by users accessing through the Sandbox option.
Warehouse Management, which includes Bins, will be available in a future update soon.
