P4314: Voucher Match is not transfering ITM to F0411 when voucher is created

Hello,

Im hoping someone can help me find the missing link to why when we create vouchers using P4314, the ITM is not transferring to F0411. I select the Purchase Order to be paid and the item number is available to be paid. Is there a processing option that drives the transfer of the product number?

We are using 9.2.5

Thanks in advance
