Hasan, it seems to me logically that we need to implement at least
one Operating Unit (obviously at subledger level) before one can
implement Mass Allocation.

In your tutorial Mass Allocation, setting profile option value for
MO: Operating Unit, I realized the value you chose was “HM Consulting OU”
. I have not yet set up any Operating Unit at subledger level yet.
Do you agree that this is the cause of the problem RaviRatra and
myself are having setting up a value for MO: Operating Unit profile
option?

Thank
