Approval

If you have the Administration Functions you can Approve and UnApprove the Cashflow.

These are all the individual rows in the CashflowForecast table relating to This Contract and This Period.
The Button then becomes Unapprove if rights are granted.

If you don't have rights to UnApprove all the buttons are greyed out. You can tell that it has been Approved because the Approval button reads "UnApproved Cashflow"
