For lumpsum discount modifier applied at group of lines level when imported using Order Import gets

Hi,

The scenario I am dealing with is as follows.

1. There is a discount modifier of type lumpsum applied at group of lines level and is set as automatic.

2. I use it to calculate price using pricing engine without entering order into Order Management forms, here the modifier works fine gives the defined amount of discount over the complete order.

3. Later while importing the order I set calculate_price_flag as 'P' (because I want to calculate taxes on the order using order import) and put record on interface tables, both lines and adjustments.

4. But while importing the order using order import, program re-calculates this discount and basically stamps the lumpsum discount amount on each line (rather than distributing the lumpsum discount over all the lines on the order).
