I am trying to create a service in salesforce CPQ selling a service that can only be sold on dates that have not be scheduled before.
The use case is: Once a date has been scheduled with a set date or date range this date range is no longer able to be sold. Ideally it would be great if a calendar would display with the unavailable dates greyed out.
You will see in the image below that all of the dates in the month are currently a dark blue. What I am trying to accomplish is when the date is unavailable to show in the lite grey ie 26,27,28,29,30 in the first line.
Currently what I am using to solve this is a price rule that throws an error whenever a date is selected that is unavailable. This is not the most user friendly way for the sales team because its "enter a date and cross your fingers that it is a date that can be scheduled".
