Why does the system allow newly approved claims to overwrite any previously approved claims?
This feature is available on the Premier and Master payroll edition.
By default, if an employee submits a claim and it is approved and committed to the Edit Payslip screen, the system will overwrite any previously approved claims.
To add new claims to the existing ones submitted within an open period, enable the following company setting.
Navigate > Configuration > Payroll > Payroll Config > Claim Settings
