Dear Venkatesh,
The Quota is generated in advance as 20 days yearly. This will generate at time of employees anniversary date.
e.g
If the employee joins on 21.06.2013, then the SL 20 days will generate when the Time Evaluation runs on 21.06.2014.
we have written the custom function to read the employee joining date and coded to generate the quota with refer to the joining date and month. There is an PCR to generate the Quota in to the defined Time type. The total Quota Value is 20 days/ yr.
Thanks
