Deski Reports: These are standard .rep files created from the full client (Desktop Intelligence) and these reports can be built using all the tools/options available in BO. These deski reports can be viewed in the Infoview/Web Intelligence but cannot be modified.
Webi Reports:These are .wid files created using the WEBI XI, and these reports can use limited tools/options available in BO(ref. comparison document on the BO website for complete difference on Webi and Deski reports).These reports can be built and viewed and modified/created using Infoview/Web Intelligence.
There are some more differences are there such as 1.In deski userdefined groups,user defined objects,user defined heirarchies,slice and dice,templetes,multiple dataprovider ,online and off line modes are there and some formula differences are there
DI :1)not more interactive 2)u need universe in ur local system..otherwise import from the repositary server 3)need BO software client version in ur local system.
wI :opposite to above and we need only server path to generate WI reports need to maintain good intra -net service no need to install any BO software ...because we can work with repository server
In Deski User defind objects are there but in Webi there is no User defined objects if you create variable and formulas In Deski Undo operation is perform many time but in Webi it will perform only one time
