Hi Team, SAPhas informed us to do the measurement of sap licenses in our DEV and PRD system and send details to them.However when i try to do measurement using USMM and press user classification i fet I am doing the selection screen modification. The selection screen is designed such as i have two radio buttons 1. header & 2. Item anb beside header radio button i have field sales document number and beside item radio button sales item number field. The problem is , how do I create an IView out of this web dyn pro application.When I try creating a WebDynpro IView it asks for a system name , Do I need to create a system in Portal for Portal ? If yes then what could be the WAS settings ? Hi Folks, in the last months I worked a lot with UI5 and as recommanded by SAP , I've used oData for the connection. Now I'm facing some limitations with it. I've discussed it with other persons who told me that they are working only with REST. That's why now I would like to create a kind a comparison on both connections: advantage and drawbacks.
