Satish,
If you installed a qlikview personal edition, go to program files - qlikview - examples - documents - executive dash board.
go through the What-If analysis tab - it is self explanatory.
what if analysis:
If the Volume changed by x%, then how will revenue affected,
what should be the organizational scenario in respect to the change in volume.
for example:
Exchange rate between dollar and rupee will change according to time.
In what-if analysis, we can analyse the scenario of revenue, if Exchange rate increases or decreases.
