The SAP error message HRPAY99_HR_PAYROLL001 with the description "One of the copied infotype records already exists" typically occurs during payroll processing when the system attempts to copy infotype records (such as payroll results) for an employee, but finds that a record with the same key already exists in the database.
Cause: Duplicate Records: The most common cause of this error is that the system is trying to create a new record for an infotype that already has an existing record for the same period and employee. Incorrect Configuration: There may be issues with the configuration of the payroll process or infotype settings that allow for duplicate entries. Data Migration Issues: If data was migrated from another system, it’s possible that duplicate records were inadvertently created. Payroll Run Issues: If a payroll run was executed multiple times for the same period without proper clearing, it could lead to this error.
Solution: Check Existing Records: Review the infotype records
