Each organization follows a specific leave year based on their company policies. The leave year can be either a calendar year or a financial year. If you try to apply leaves between two leave years, then the following error displays: You must apply leave separately for each leave year.
For example: If a company is following a calendar year as a leave year, and you want to apply for leave from 30th December to 3rd January, you will get this error.
To rectify this, you must apply separately for leave in both years.
