I would like that account managers to be able to open up a forecast tab, and they see a spreadsheet that able to edit one field only - "number of units".
The spreadsheet lists their accounts down the left and 13 months across the top and they adjust their forecast for our two primary products (Product A , Product B).
If you have the talent to make it by 3-5 hours you can take this task.
Please remember it should look as excel sheet, each user can see his own forecast (Custom object) and CEO is able to see all account manager forecasts.
Thank you in advance.
