Disallowing Users to Pick Dates in the Forecast Date Dialog Box
The Skip Existing Forecast Series Date user property configures Siebel CRM to not allow the user to pick a date in the Forecast Date dialog box in a Forecast view. It applies this restriction only if a forecast already exists for the current user for the current date. It can contain one of the following values:
Y. Do not display the date. The user cannot pick another date.
N. Display the date and allow the user to pick it.
You can configure Siebel CRM to modify the value for this user property, but not to deactivate it or to create a new instance of it.
