Issue with EOS calculation for Saudi Arabia payroll PY SA

Hi Expert,

My client requirement for End of Service settlement (EOS) is, the unpaid absence in /847 should be considered in calculation of EOS if it is above 20, means he is giving a grace period of 20 unpaid absence.

Ex:

1. Total service days =  1150
2. Unpaid absence in /847 = 60
3. Now we have to minus 20 from /847, that is = 60-20 = 40
4. This 40 should be minus from total service days. 1150-40 = 1110

Can you please do needful.

Thanks and Regards

Suresh
