Making Retroactive Changes
The system checks all Organizational Management actions to determine if they require changes to be made to personnel data with a greater retroactive effect than the "Earliest retroactive accounting period". This period, which is defined in Personnel Administration, prevents subsequent changes from being made to specific payroll sub-units.
If integration is active, the earliest retroactive accounting period is also valid for Organizational Management transactions, if it also affects Infotype 0001. Any attempt to enter data with a retroactive effect greater than the earliest retroactive accounting period is then rejected by the system.
