When you use the Core HR module, you can create recipes to notify you of some changes in an employee's profile. For example, if someone updates an employee's home address in their profile.
If you receive these notifications after employee's payslips have been uploaded from Sage 50 Payroll, this is because of the new employee data synchronisation between Sage HR and the latest version of Sage 50 Payroll.
When you upload payslips, the following details in Sage 50 Payroll automatically update the same fields in Sage HR so that the information matches:
Forename
Surname
Address
Postcode
Bank name, account name, account number and sort code (primary account only)
Phone number
Mobile phone number
Marital status
Country
If you have a recipe set up to notify you about changes to one of these fields, when you upload payslips, if you do get a notification, then it is because the fields didn't exactly match, and the sync has updated Sage HR's information.
This won't happen again when you upload payslips unless you make changes to these fields in Sage 50 Payroll.
