Purge AP - Voucher-Payment Data

Hi.

I am searching some related document for Purge of AP (Voucher & Payment Data). Currently we are using AP Archival Process but want to enhance it with using Purge AP data as well. I am not sure if we can do it in AP as well or not. I am aware that GL Purge is possible and documents are also available.

Kindly share me details and starting point so that I can start going thru same and try to use purge process as well.

Thanks.
