Change in Leave policy assignment in mid period

[sanjay141986]

Case Scenario: Changes on assigned Leave Policy

1. A full-time employee has been assigned a Leave Policy based on a period of 1/1/2023 to 31/12/2023
2. Annual leave allocated is earned leave basis (e.g 22 days) in this full-time Leave Policy
3. Later on, the same employee has a change in employment type from full-time to part-time which triggers changes in leave policy (period year of 1/5/2023 to 31/12/2023)
4. A part-time Leave Policy should be granted to the said employee

Limitation in the System

1. System is NOT ALLOWED to assign new policies without canceling the old ones which will also trigger to cancel of all the "submitted" leave applications of the said employee
2. The above limitation has caused the client can't traceability as well as the employee's lifecycle history within the company

Expected Scenario

1. If any employee wants to work from Full time to Part time then System should allow changing the Leave Policy Assignment accordingly.
2. If any employee switches the department in between running periods and every department has a different leave Policy then in this case also the system should allow changing the leave policy
