Within the Employee Security module in Alliance, there is a menu option Erase Employee Data.
This option was added to support compliance for the European Union’s GDPR (General Data Protection Regulation). According to the European Commission, personal data is any information relating to an individual whether it relates to his or her private, professional, or public life. It can be anything from a name, a home address, a photo, an email address, bank details, posts on social networking websites, medical information, or a computer’s IP address.
This option removes employee’s data from all records in the system. Please be advised that it is a very heavy process and it should only run during the non-working hours as it affects many tables, etc.
Other than situations where this is needed for GDPR, the general process is to simply set the employee to Inactive in the system.
