The SAP error message E_ACTION167 indicates that there is an issue with the "Relieving Date" in relation to the "Hire Date" of an employee. Specifically, this error occurs when the relieving date (the date an employee is officially leaving the organization) is set to a date that is earlier than the last hire date of that employee. This situation is not logically valid, as an employee cannot leave before they were hired.
Cause: Data Entry Error: The most common cause is a simple data entry mistake where the relieving date is incorrectly entered as an earlier date than the hire date. Incorrect Employee Records: There may be inconsistencies in the employee's records, such as multiple hire dates or incorrect historical data. System
Configuration Issues: In some cases, there may be configuration issues in the SAP system that lead to incorrect validation of dates.
Solution: Verify Dates: Check the employee's hire date and the relieving date entered
