How to Calculate Billing Quality

Question

Hi all,
I need to calculate %billing Quality Defect in BMM layer (Business layer). The logic for this is %BQ Defect for the P&L for that particular month. For each P&L for a given month, %BQ Defect = No of invoices with defects (6A, 6C, 6D, 6E, 6H, 6J, 6L, 6N, 6O, 6S, 6T,6V, 6X)/Total no of invoices.
How to write logic for %BQ DEFECTS. I used this query in SQl
select count(a.open_item_number)
from crmps01load.crmps_open_item_monthly_arch_f a,
crmps01load.crmps_pastdue_reason_cat_d b
where a.CRMPS_PASTDUE_RSN_CAT_DIM_KEY = b.CRMPS_PASTDUE_RSN_CAT_DIM_KEY and b.PASTDUE_REASON_CATEGORY_CODE='6'
and a.CRMPS_PASTDUE_RSN_CAT_DIM_KEY in ('141','142','135','143','144','145','148','149','150','166','168');
so Could any body help how to write this above convert the above logic into OBIEE BMM layer.
thanx in advance
