we are using the standard PO approval flow, not using a workflow. how do we stop the PO pdf to be sent to the supplier upon approval?

AI generated answer (using internal Slack threads):

To stop the Purchase Order (PO) PDF from being sent to the supplier upon approval when using the standard PO approval flow, you need to ensure that the 'Send Transactions Via Email' preference is not ticked in the Vendor record. Also, make sure that the email box (beside the email address) is not ticked in the PO. If these settings are correctly configured and the issue persists, it might be due to some other configuration or a script that is triggering the email. You may need to review your setup and scripts to identify the cause. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
