How to add a salary sacrifice deduction using percentage rather than fixed amount

Hi everyone,

I was wondering if it was possible to add a deduction line item using a percentage instead of fixed amount. I'm having difficulty finding out if this is possible or not using the documentation.

When we look at the details of a payrun, deduction items have a "IsPercentValue" attached to them. Is it possible to add this field when creating the deduction?

Thanks!
Jacob
