PO Change Acknowledgement Outbound is not triggered when SSD got updated on sales order lines

Hi Team,

As per the below 24C update "Send Oracle B2B Purchase Order Acknowledgements to Your Customers" we can send PO change acknowledgement message to customers when any of the terms (items, quantities, dates, and other terms) change on sales orders.

We completed all the collaboration messaging setups according to the above update. When we submit a sales order PO acknowledgement out document (EDI 855) is triggering successfully. After this document is generated we updated Schedule Ship Date on fulfilment lines. But PO change acknowledgement out document is not generated once the SSD is updated.

The PO change acknowledgement out is generated when we created a revision and updated any of the above attributes on sales order.
