IsPayment()

Determines if a transaction is a payment.

Syntax

IsPayment() --> lPayment

Returns

Logical TRUE is returned if the transaction is a payment, otherwise logical FALSE is returned. If the invoice.dbf or accpay.dbf database has not been opened by the form, logical FALSE is always returned.

Description

Determines whether a transaction is a payment and returns logical TRUE if so. Only transactions held in either the invoice.dbf (customer transactions) database or accpay.dbf (supplier transactions) database can be payments. The form must therefore open either the invoice.dbf or accpay.dbf database. Ensure that IsPayment() is used in the specific body that opens invoice.dbf or accpay.dbf, otherwise logical FALSE will always be returned.

In the event that both invoice.dbf and accpay.dbf are opened by the same body at the same time, use the alias operator to refer to the one you need to query.

Example

If invoice->(IsPayment())

Echo('Customer transaction is a payment.')

Endif

If accpay->(IsPayment())

Echo('Supplier transaction is a payment.')

Endif
