Blanks display in query

I have created a Multiprovider tying up InfoObject 0COORDER and a custom DataStore. When I create a query, I see blanks in the places where there is no record. In the overall results the available days show up as 28 days and utilization as 90% for the obvious reason that there are no records for EX2345 and EX5234 Now my Client expects to see a report in the following format:

Order No Order Type Order Qty Available Days % Utilization

EX1234 Excavator 25 Days 28 Days 90%

EX2345 Excavator 0 Days 28 Days 0%

EX5234 Excavator 0 Days 28 Days 0%

Overall

Result 25 Days 84 Days 29.6%

Available days = 90% of Calender month’s days (generated through Formula)

Is there any way to bring the report to Client's expectations. Your input would be highly appreciated. The development is in BI 7.

Thanks,
