Absence update history not available

Summary:

Currently when the employee update the existing absence record and submit it, the back end does not hold both the data on the absence entry table.

Unfortunately, the back end tables only shows the updated values of absence records, We would like the old value and the overwritten values of absence record to be pulled through OTBI report.

Adding such fields would significantly facilitate the daily work of Managers and HR in our organization.
Also this data needs to be available on back end or on tables so we can create reports
