Live office is separate license with 4.1 BO Enterprise as per my SAP sales person
May be the license model is changed in latest version. I worked in BOXI3.1 and there LO license came with BO Enterprise license, no additional license was required.
I have discuss with other Dashboard developer they advise me I need to completely change backend side since I am using the Add Query as data feed ?
Changing LO connection with query browser might cause you significant change in design. That is why I suggested to use BI as Web Service, where you can re-use the existing webi reports used for LO connection.
