Reproducing the Issue

  1. Go to the Purchase Requests and Orders work center
  2. Go to the Purchase Orders view
  3. Select the relevant Purchase Order
  4. Select New PO Acknowledgement button 
  5. Adjust the Delivery Date and Save the acknowledgement


There is a business configuration setting called Purchase Order Output Control Settings. Here you can maintain Purchase Order Send Output Control Settings;

1. Purchase Order Send Email Control Settings
2. Purchase Order Send Output Control Settings

In the Purchase Order Send Email Control Settings, You can configure the e-mail ID settings for different party types, if the purchase order communication to supplier is via email. Here you can see that Email ID Settings for Purchase Order Output is set as Supplier under Send to column. Which means any changes in the purchase order will inform the Send To party i.e Supplier. Hence the changes has been informed to the supplier.

Similarly Purchase Order Send Output Control Settings will be triggered, when changes to ordered purchase order is communicated to supplier (via email, fax or post) only if there is a change in the values of the attributes that are selected below. You also need to take care of dependent attributes. For example, when you change quantity, it automatically leads to a change in net value and taxes at item and header. These settings will not be applicable in case ordered purchase order is updated and approval is triggered.

Under the available Nodes heading, you can select Item and on the right hand side you can see Available Attributes.
Here you have selected the Delivery Date check box. So any changes to Delivery Date attribute, will be communicated to supplier.


If you do not want system to communicate the changes to the supplier, you can deselect the attribute Delivery Date and save the settings.

also check the changes tab of Purchase order to see other fields that also gets changed when you make changes and uncheck them as well in Purchase Order Send Output Control Settings.
