Supplier inactivation understanding

Summary:

I have previously asked and not received a response. I need to know the exact definition of 'no transactions' when running the supplier inactivation process.

We have examples of suppliers that are not being closed by the program - they have no requisition activity, purchase order activity, invoice or payment activity or master data changes and we cannot understand why they are not closing.

I cannot find any clear and complete definition of what 'no transactions' means.

Can you give some clarity as to the specific dates and activites that are being considered when referring to 'no transactions'.

I received this response previously: The job looks at each supplier’s last transaction date (based on the transaction types the process is designed/configured to consider).
