Aggregation in Cube

HI,'

 

Am loading flat file to info cube with delta update say

 

Customer     product     Category     Qty      Price

c001               p01             Cat1     10          1000

c001               p02               Cat2     20          2000

 

and perform a full load the the same replicates in cube and then i edit the flat file and run the info package and DTP with delta say am loading

 

C001    p01   cat1 20 2000

 

so now the records should be aggregated right? tell me if am wrong am not getting the concept right make it clear to me

 

i expected the data in cube would be

 

c001               p01             Cat1     30         3000

c001               p02               Cat2     20          2000

 

But the result was

c001               p01             Cat1     10          1000

c001               p02             Cat2     20          2000

C001              p01             cat1      20           2000

am really confused so make it clear when does aggregation happen but i found another thing that if i have data like

c001               p01             Cat1     10          1000

c001               p02             Cat2     20          2000

C001              p01             cat1      20           2000


initially in the flat file and if am loading the above 3 records for the first time into cube then the records are getting aggregated and result appears as

c001               p01             Cat1     30         3000

c001               p02               Cat2     20          2000


am really not getting the concept please help me out


Thanks,


Madhu Nair.
