Hello Madhusudan,
Asn Suggested by Ramesh, the data in the Infocube F table is shown or displayed request wise. This is why you get that behaviour . I think you aggregated the records as per the key fields. that is basically aggregation.. a concept that is used for optimizing the Query performance.
Please refer below link, which is on Aggregates., and refresh your concept on that
Performance Tuning for Queries with Aggregates:... | SCN
It has similar type of Example as you mention above I( Country Vs Sales)
Hope this Helps...!
