Back-end table for Vacation Rule delegation and Task delegation

Hi Cloud Community,

We have an audit requirement to get details on the Vacation Rules set by the user and based on the certain criterion it will be marked as compliant / non-compliant with company policies. The ask is to get vacation rule setup by the user based on any given invoice at hand.

While there is a standard report for getting the vacation rules information - 'Employee Vacation And Delegation Rules Report'. However we need get the data model behind this report, so that the same can be utilized for a custom report.

Is there any way this model can be accessed? Any reference to the relevant table for Vacation Rules would also be helpful.
