Ex. some person number 12345ABC applies for leave (12/04/2021 - End date not determined) and works 5 days a week. So, data fetched in table(anc_per_abs_daily_dtls) is from 12/04/2021 to 11/04/2022. In days which are working for the employee it will return abs_days as 1 and 0 for non working days. small snippet of the data from table has been attached below.
