How is an absence record(per_absence_attendances) linked to element entry(pay_element_entries_f)?

Hi,

When an absence record is created, an element entry gets added in the same period for that absence record.

Accordingly there is one row added in per_absence_attendances and one row for the assignment in pay_element_entries_f.

When we create two or more absences, the similar process happens for every absence record.

But how do we identify, which element entry is for which absence entry?

Kindly suggest, if any other table is present which links the above two tables to give a one to one relationship of absence details and element entry.
