Field help (TPYSNS) 

Select the payment sign.

If you select Expense or Revenue, this field does not display in the payment header screen in payment entry. In this case, the user knows that the payment transaction is always an expense (issued cheque for example) or always a receipt (cheque receipt for example).

If you select Unspecified, you make the selection in the payment header as Expense or Revenue. This makes it possible to create only one payment transaction used for both receipt and expenses as in cash entry for example.

Requiring payment authorization only applies to expenses or unspecified types and when the Remittances and Bank file check boxes are selected. Use the PAYAPP - Payment authorization parameter to grant users the ability to approve payments.
