ap_supplier_sites_int status is null

Hello

We have transferred more than 28000 invoices and sites from an external system to Payables, but those invoices were rejected because the supplier sites could not be interfaced due to the volume of the supplier site is very large (28000 sites).
The status in the ap_supplier_sites_int table is NULL.

So we can't purge this table (note 2189399.1).

Now we want to transfer 5000 invoices at a time (instead of 28000 one shot).
My question is: will the system allow us to transfer the 5000 sites without blocking or will it try again to transfer the 28000 sites which are now with the null status.
