understanding required on Work schedule rule parameter under evaluate absence process

Sumit Arora-Oracle

In 22A upgrade oracle introduce new work schedule rule parameter in evaluate absence to refresh the issue in absence duration impacted due to work schedule change.

Needs understanding on below functionality. What is the difference and how these rules will work with each option?

1.Based on date rule - asking for no. of day as input

2.Based on last run

3.Based on reference date - asking for reference date as input

Regards,

Sumit
