EDI 855 IR code in line, cancels PO header

Summary:

We are in a weird situation because of this behavior.

In Configure Procurement Business Function, the flag "Communicate purchase order changes" is turned Off for our production.

Because of this, when a change order is created in the system, the Required acknowledgement flag at the PO header turns to No when the change order is submitted. For the original order, the required acknowledgement is Yes.

Content (please ensure you mask any confidential information):

In case of EDI Orders, most of our suppliers do not acknowledge all the lines in the same POA/855. They send more than one acknowledgements for the same PO. Due to the above mentioned configuration and Oracle behavior, only the first acknowledgement updates the PO.
