Hi Pawan,
When you created the custom order series key figure, did you assign it to a "category group " ? Also when you add this key figure to the planning area, you will have to include the "category group" as well.
Also include the key figure function 1003 in your key figure and remove it from the "Additional Forecast- 9AAFCST" keyfigure.
This should allow you to edit the values for this order series key figure.
Regards,
Mitesh
