Changing Quantities in the Details Screen 
When you access the planning table, the production quantities are ready for input.
If the production quantity consists of several run schedule quantities, the system displays a dialog box where you select the planned order you want to change.
A dialog box appears with the detailed information of the order you selected.
You are returned to the planning table and the system has adopted the changed quantity specification. However, the system only makes the changes as a simulation.
The system does not update the database with the changes until you save the data.
