LIS-Flexible Analysis (MCSG)

Hello Experts,

1.  In standard SIS, can we get the key figures in percentages?  If yes, how to do that?  My client wants the SIS report with percentages like Net Profit%, Gross Profit%, Sales Returns%, Discounts% etc.,

2.  Please let me know how to configure the SIS-Flexible Analysis?

3.  What is the use of Flexible Analysis, do we have the flexibility to show the report with percentages like Net profit% etc stated above.

I have googled for the above queries, but I could not get the answers to my queries.

Thanks,

Sreehari.
