Hi Syl
Are you using Reckon Accounts' default "Holiday Loading" Payroll Item or have you set up your own?
The default one has been correctly configured to calculate when using a "Holiday ..." Payroll Item & won't affect actual Leave hours accrued or available. However, if you've set up your own instead, it has probably been incorrectly configured. If this is the case, I would recommend using the default "Holiday Loading" Payroll Item only.
