Replenishment Order Confirmation Not Triggered when Published in SNC

Hello,

Replenishment Order Confirmation XML Message is not getting created/triggered once the supplier did the confirmation from his end for the Work Order against the Purchase Order in the SNC Web UI screen and further which is not updating the Order Acknowledge details in the ECC system under 'Confirmation' tab in the ME23N transaction. But in the meanwhile Replenishment Order Notification XML message is getting succesfully triggering from the SNC system. So, Please let us know what could be the reason for ROC not getting triggered in the SNC system.

Thanks & Regards,

Pavan
