If you are working with suppliers and wanted to be able to track what has changed on a purchase order as it’s being updated then you have a few options. You can post the confirmation as that will be a copy of the details at the time of confirming. You could use database log but that is generally not recommended on transaction tables for performance reasons. The other option specific to procurement is to turn on change control. This can be turned on for all purchased or for specific vendors or for specific orders. You can then use a work flow for approval as well. When you make changed then you have a compare function to enable you to see what has been changed on the purchase order.

Here is a quick look at how that works.
