Hi Rajesh,
Let us assume a DATA SOURCE for sales with delta AIED
In DSO:
EMP Id SALES QUAN SALES AMT
001 2 20
002 4 40
In CUBE:
EMP Id SALES QUAN SALES AMT
001 2 20
002 4 40
if sales order is changed and quantity is updated to 4 for EMP ID(001)
EMP Id SALES QUAN SALES AMT
001 4 50
DATA in DSO becomes
EMP Id SALES QUAN SALES AMT
001 4 50
002 4 40
DATA IN CUBE BECOMES
EMP Id SALES QUAN SALES AMT
001 6 70
002 4 40
But DATA in cube should be 50 for SALES AMT and QUANTITY should be 4.
