The SAP error message HRPADDERR010 indicates that there is an issue with the retroactive accounting date in the Human Resources (HR) module. Specifically, the error message states that the retroactive accounting date you are trying to set is the same as an existing retroactive accounting date for the employee.
Cause: This error typically occurs when: You are attempting to change the retroactive accounting date for an employee to a date that is already set as the retroactive accounting date. There may be existing payroll results or infotypes that are already using the same retroactive accounting date, which prevents the system from allowing the change.

You can do this by navigating to the relevant infotypes (e.g., IT0003 - Payroll Status) or using transaction codes like PA20 or PA30 to view
