Enhance item preview in UWL
as part of my requirements I need to enhance the item preview of UWL in the Portal with a new piece of information which is the material group of the item.
The line which is selected is a purchase order and the preview shows the list of items of the purchase order. We want to enhance this list with some more information. Should this be done in UWL or on SAP (back-end side)?
I think it would be more convenient to make changes in the back-end for the Preview option, as the preview text will be same in both SBWP inbox of the user and in UWL inbox from Portal.
You can refer to the following link which has a demo and talks about how Work Item previews can be modified: http://help.sap.com/saphelp_nw70/helpdata/en/90/6faf8be73b11d2a6360060087a79ea/frameset.htm
