Multi Level Pegging

I am on Vantage 4.8 I have a View Multi Level Peg from sales order/line/rel.
can someone start me off on creating a report as there appears to be no existing report, I have BAQ & Crystal.

we make direct to order I have created a O/s sales showing all relevant direct linked jobs or suggestions, I now need to take it further & show jobs created for any shortages

Some help using the pegging data files to produce a multilevel report seems a good start
