I apologize for the confusion. The Show Bank Details does not prevent auto-creation of Suppliers.
What it does, however, is prevent the QBO AI engine to come up with it's own "description" of the transaction.
For instance, I had a transaction with the bank details "Shawcliffe Petro-Canada".
The QBO AI looked at the bank details and came up with it's own description: "Shaw's"
The only way to prevent the AI and force the original Bank Details to be populated, is to enable the "Show Bank Details" option.
This does not prevent automatic creation of the Suppliers, but proves that QB Support statement that QBO doesn't alter the bank details - is a flat lie. Their AI does, when "show bank details" is unchecked.
