CAUSE… For W Type Batches, vouchers cannot be created without an associated payment. The Payment Without Voucher Match process uses the W batch type, and creates a voucher for the payment being entered. Canceling out of the payment will cancel the voucher also.

RESOLUTION… Enter both payment and voucher information for a W type batch. To enter vouchers only, use a voucher entry method such as Standard or Speed Voucher Entry that does not have processing set to generate payments automatically. –
