Using this step-by-step approach, you can avoid problems when you move, delete, or add holidays in your calendar.
The holiday calendar is the base calendar in the Time Management module for time and payroll calculations. Changes in an existing holiday calendar affect several infotypes. Unless you regenerate the work schedules after the changes, the system does not reflect the changed holidays in infotypes 0007 (planned working time), 2002 (attendances), 2001 (absences), 2050 (annual calendar), 2051 (monthly calendar), or 2052 (weekly calendar). Also, it does not calculate absence quotas correctly in infotype 2006 (absence quotas).
Holiday calendar changes are quite common in many countries. By implementing those changes with my time-tested methods, you can avoid many of the issues that the changes raise, such as incorrect calculations in absence quotas and inconsistent annual or monthly calendars. You can use this method starting with Release 4.0B through SAP ERP 6.0. The configuration I’m describing takes place in the Time Management module.
In my example, a company wants to move the floating Diwali “festival of lights” holiday from November to October. The change affects infotypes 0007, 2001, 2002, 2006, 2050, 2051 and 2052. If you use the following steps, the system reflects the changes in all those required infotypes:
