Exclusion of customer hierarchy nodes

Hi guys,

I have a requirement for customer hierarchy and discounts. I have created a 2 level hierarchy using VDH1N

Level A - Discount 10%

Level A1 Level A2 Level A3 Level A4

Cust A1(sold to) Cust A2 (Sold to) Cust A3 (Sold to) Cust A4 (Sold to)

The client wants only A1 and A2 to inherit the discount 10% and not A3 and A4. Now I have unchecked the relevant for pricing indicator on the billing tab fpr Level A3, Level A4 as well as Cust A3 and Cust A4 but yet when I create an order for Cust A3 It still inherots the 10% discount and same for A4 (condition type HI01)

Any suggestions what I can do?

Thanks,

Rashmi
