2879125 - My Outbox - original values no longer visible

You have activated flexible workflow for Purchase Orders. A Manager will receive Purchase orders for approval in the 'My Inbox' APP. The approving manager will also have visibility of documents they have handled via the 'My Outbox' APP. If a user changes a Purchase Order, it will again submitted for approval. Assume it is released a second time. When the approving manager checks the history via the 'My Outbox' APP the 2 entries for the Purchase Order both show the changed values of the Purchase order item. The original values as they were when the document was created are no longer visible to the approving manager in 'My Outbox'.

The Generic APPs 'My Inbox' and 'My Outbox' only show a factsheet with a very limited view of the business data. The factsheets will always display the values directly from the database, so the current values are always displayed. Changed values are not retained for display in these APPs.

To view changes, an approving manager can view the change log in the 'Display Purchase Order - Advanced' webgui tile.  Path Environment > Document Item > Item Changes
