ST/OT - Business Unit Invalid Error

Hello Everyone,

I am trying to create a simple ST/OT Order.  But it gives me Business Unit Invalid error, Currency code error.  Attached is the screen shot of the errors.  I checked the set ups for Business unit in F0006 and Address book, not sure what is missing.

The ST and OT from and To branches are set up in Address book.  The currency set up is also exists.

I am technical, so may be it is a simple set up. But I have to fix this set up issue.

Thanks
