Attachments maintenance on suppliers attachment, voucher attachments...etc.

Do you take advantage of PS attachment functionality? How do you handle attachment maintenance, such as suppliers attachment, voucher attachments...etc.? How do you retrieve attachments for record retention requirement AFTER attachments are archived? Any inputs are much appreciated. Thanks!

@Charity Liu we use PS attachments for invoices and all supporting documentation for journal entries in PS. We have not had the need to archive the attachments yet, as we went live with PS 18 months ago. We are looking into ways that we need to meet regulatory requirements for WORM storage, so hopefully we can share more info later.
