Gregorian Date to Hijiri Date Conversion

Business Requirement.

In SAP Saudi Implementations, the HR Module that has lot of Dates that are being captured for the employee.  However, in the reports and/or display the respective dates are being displayed in synch with Hijiri Calendar and not in regular English (Gregorian) Calendar.  So we need a conversion from Gregorian Date to Hijiri Date.

Hijri Calendar - The Hijri calendar is a lunar calendar, consisting of 12 months of 354 or 355 days. As it is a lunar calendar, there is an annual drift of 10 days.

How We implement.

1. Go to SE37.
2. Create a new function
3. Provide Input parameter specification
4. Provide Output parameter specification
5. complete the Source code.
