AR refunds to AP: AP voucher payment Sync with AR,BI or PC

Hello All,

We are testing to process the AR refunds through PeopleSoft system to AP for payment to customers.

The Request Refund item loaded correctly to AP, the item for refund. The payment to the customer is posted with success after the voucher Build and voucher posting.

I did run the Cost Collection > Payables process PC_AP_TO_PC, but the PS_VCHR_ACCTG_LINE.PC_DISTRIB_STATUS is set to 'I' (ignore)' and to 'N' to be select by PC_AP_TO_PC.

We are wondering if they are other steps to Interface or Sync Payables to BI, AR, PC or Customer Contracts in order to complete the process or to update the billing Plan history for the Customer with Refund payment?
