Hi Giri,
Please refer the below document on step by step process to generate quota in time evaluation PT60.
Grant of Absence Quotas in Time Evaluation
You will have to define step 7 from the given document.
Step 7: SPRO > Time Management > Time Data Recording and Administration > Managing Time Accounts Using Attendance/ Absence Quotas > Calculating Absence Entitlements > Rules for Generating Absence Quotas > Determine Validity and Deduction Periods
I hope this resolves your issue.
Thanks and regards,
