How to avoid creating a revision or a change order when PO line price is changed through a web service

Content (required):

Hi,

We have a requirement not to create a revision or a change order when we change the PO line price through webservice. However, the revision should work the way it is when the change is through UI. Currently, there's a revision getting created every time when the change is from UI or through the SOAP web service. As mentioned in the Oracle Doc ID 1321055.1 , it is possible to not create a revision if the change is internal (if attributes are unchecked). However, this is applicable only for a limited number of fields and "Price" is not part of the updateable attributes.
