Looking for good strategies to Analyze VBEP with HANA

Can someone help me to get into the right direction on VBEP Analyzis?

At this point I'm not really so much interested to report on the schedule lines details but I need to get them analyzed to answer the following questions:on order/quote line items utilizing HANA:

1. % of Line Items fully Confirm as Requested  (is the sum of the confirmed qty >= the requested quantity at the requested quantity date)
2. like above for Committed Date (EDATU where ROMS1 > 0)
3. # of Days late to Committed date (if the sum of the confirmed qty is less than the committed quantity (ROMS1) at that committed date, find the confirmed quantity date that would satisfy the committed quantity and calculate the date difference so we get the # of days we're projected (or were) late).

Any guidance, strategies or colaboration would be highly appreciated.

Thanks

Elmar
