This activity may be done by the budget/forecast owner who approves the budget/forecast
directly, or by using a pre-defined approval routing where individuals can approve
the budget/forecast in parallel or in sequence.
A budget/forecast may
be approved either from status Reviewed if no approval routing exists
or from status Approval in Progress if approval steps have been
defined on the approval routing linked with the budget/forecast.
The Status Approved is assigned to the budget/forecast version.
