To request a PTO
Go to the Paid Time Off tab on the TimeTracker application and click the + button, you see the PTO type field, with the number of PTO days available for you. (You see the available PTO days on the screen only if the Administrator at your org has updated the PTO status for you).
On the Request, PTO screen, enter the PTO Type requested, Start and End Date and Time, and the Out of Office instructions and click the Ok button to submit the PTO request.
Once you submit the PTO request, your Manager that approves the PTO sees your PTO request in Salesforce and can approve the PTOs for you.
You can also request a Half-day PTO, by selecting the Check box in the Request PTO screen.
