Purging of AP_INV_SELECTION_CRITERIA_ALL

We run Payables. We purge using AP Purge (APXPGSEL then APXPGDEL firing lots of APXP7PRL). We purge once the last_updated_date is more than 15 months.

The core AP tables of AP_INVOICES_ALL, AP_CHECKS_ALL, AP_INVOICE_PAYMENTS, AP_INVOICE_DISTRIBUTIONS, AP_AE_LINES and the rest are being purged correctly.

We've noticed that AP_INV_SELECTION_CRITERIA_ALL is not being purged. Should AP Purge manage this table? If not then what does?

Thanks
