Ofsc validation to check if current date is greater than start date of an Activity

Summary:

We would like to implement a validation in Oracle Field Service Cloud to ensure that a field is made Read Write only when the current date is always greater than the activity’s start date.

We want to use such validations to prevent Technicians from Ending the activities in field service on the next day incase if they have left them in started state the previous day.

Could you please assist us or provide guidance to achieve this in field service application.

Note: We don’t want to change the setting of allowing users to update activity data from past, that needs to allow past dated updates.
