How does the system calculate the price for the item in OM

Hi All,

I have done a setup in advanced pricing module using price breaks and these are the values

Item: Test 1

Line Type: Price Break Header

Price Break Type: Range

Application Method: Unit Price

Price break

Value From        Value To         Price

0                          3                  900

3                          5                  850

5                          10                 700

Now in the sales order the line details are as follows

Ordered Item                  Qty               Unit Price
Test1                             1                      900
Test1                             3                      900
Test1                             4                      887.50
Test1                             5                      880
Test1                             6                      850
Test1                             7                      828.57
Test1                             8                      812.50
Test1                             9                      800
Test1                             10                    790
Test1                             11                    718.18
Test1                             12                    658.33

I was expecting a normal price break where in if the quantity was between 1-3 the price could be 900 and if its between 4 - 5 its 850 and 6-10 its 700 and anything above 10 would be priced at 700.
