Pricing error while creating billing

Hi Experts,

We have created 2 table in access sequence.

20    Sales org./Distr. Chl/Bill to/Variant 

30    Sales org./Distr. Chl/Division/Bill to/Variant

Exclusive indicator is checked for both the tables and condition record is maintained for both.

Now when we create an order in combination with 'Sales org./Distr. Chl/Division/Bill to/Variant'

system is not picking price from 30 table it is picking for 20 table.

What is the reason?? is it happening because we set exclusive indicator for both the table 20, 30 please clarify.

Thanks in Advance,

Ali
