Stop PO change outbound XML from SNC to ECC

Hi SNC experts,

When I'm doing confirmations from SNC,the XML message "ReplenishmentOrderNotification_Out" gets triggered first and then the "ReplenishmentOrderConfirmation_Out" is triggered.

We need to stop the XML for PO change from SNC to ECC that gets triggered with the confirmation i.e. "ReplenishmentOrderNotification_Out"....Can anyone please let me know how to do that?

Thanks in advance.

BR,
