Supplier Inactivation Draft Report - Process Questions

Hi,

I have extracted the Supplier Inactivation Draft Report and cross-checked it against the payment history.
Based on my review, the system is identifying suppliers that have not had any transactions in the last 18 months.

Could you please help key eligibility, whether the system will select suppliers for inactivation only when both of the following conditions are met?

The supplier has had no transactions in the last 18 months; and
The supplier has no open balances or outstanding liabilities.

Also, can you please advise on this query?
I am assuming that the system will inactivate the vendor at profile level if none of sites are having transactions in last 18 months. Pelase cofirm
