NEGATIVE_DEDUCTION is an optional field used to determine how a negative deduction (i.e. a refund or 'credit' to the employee) will be processed.
* 'Add Back To Gross' returns the deduction to the employee by adding it back to the Employee's gross pay, enabling it to be used to cover other deductions.
 ‘Add Back To Net' returns the deduction to the employee, but does not enable it to cover any other deductions (e.g. strict refund). This option tends to be used for items that are not normally part of the gross to net calculation, such as allowances or expense reimbursements. When a recoverable advance is set up as a negative deduction, the Collect Back toggle must be turned on in order to generate an arrears transaction to recover the amount advanced on a subsequent pay.
