Promised Date Changes forces Approval Workflow - would like to stop it

 Our Buyer Planners change the Promised Date on thier PO's frequently.

It takes several screens for them to do this and then the Approval Workflow process takes over.

EU selects PO Buyer responsibility then opens PO Summary. Enters PO number <ENTER> then opens the PO Select a release. Go to Promised Date and enter a new promise date. Click on Save.EU receives Warning message about a new document revision and clicks on OK. They then click on APPROVE - enter notes on Approve Document screen and clicks on OK. This starts the PO Approval workflow process. Ideally the EU would like to be able to click on SAVE and not have to do anything else.
