InfoSet vs Multiprovider Scenario

Question

Hi experts,
I have read some doc about Infoset and multiProvider. For more clear about them, I have find some scenario which should be use Multiproveider only (ex:plan/actual, slow moving product,..) but I can't find out  which scenario we  can use InfoSet only instead of Multiprovider. Anyone pls tell me to understand clearly about InfoSet.  10 points for helpful scenario

Hi..
InfoSets allows reporting on several InfoProviders by using combinations of InfoObjects (master data-bearing characteristics) and ODS objects via a join condition.
An InfoSet can have following join conditions
Inner Join
Left Outer Join
Inner join and left outer join are only different in the situation where one of the involved tables does not contain any suitable record which meets the join conditions.
Consider ODS object that contains a characteristic PLANT alongside key figures in its data part. In an InfoSet, a join between this ODS object and the characteristic PLANT is defined to enable the attributes of PLANT to be accessed in a report.
If an inner join is now used and if an ODS object record contains a value for PLANT for which they is no entry in the corresponding master data table, this record is not included in the results set. Correspondingly, the key figures of this record would not be considered. 
If, on the other hand, a left outer join (ODS object left outer join PLANT) is used, the affected record is considered. However, in this case, all attributes of the (non-existent) characteristic PLANT are initial. Which behavior is correct depends on the type of the evaluation required. Both cases can make sense.
