Hi Raj,
I understand you want to know the leave balance available till date as mentioned 'leave accrued by a leaver to date'.
You may go to the worker form, 'Leave' tab and click on Manage leave - View time off

Here, go to 'Balances' tab, Current balance will show you the leave balance available till date

Also, when an employee, Request time off, here you can find the Available balance till date.

I hope this answers your query.
Thank you for using Microsoft Dynamics 365 Communities!
