How to set Billable field to true automatically after 10days

[Research]

Hi

All can anyone guide me.

Automatically set the Billable to true using business rule based on 10 days timeline (part requirement task closure)

Please can you guide the script 

appreciate

Thanks

You'll need to set up a scheduled job to run the BR each day, to see if the threshold has been breached...it's more than just a script on a BR. Could you elaborate on " based on 10 days timeline (part requirement task closure)" -- do you mean that you want it to set to billable if open 10 days after the "opened" date?
