PSP WaterFall and RepriceAll, reprice all orderlines with same Price List Item ID

Hi all,

During the use of the PSP WaterFall, I encountered an issue regarding setting the Prices on Order Lines.

The issue:

I have 2 active Order Lines under 1 Order.

When I open the WaterFall for one of the order lines, both orderlines are repriced, using only 1 price list item.

Whilst typing this issue I also tried the RepriceAll button for the orderlines and the same issue occurs.

Where and how can I make the proper adjustment to get each individual orderline priced with its own price list item id?

Because:

When I use the Reprice button on an order line 1, it returns the right prices on the orderlines using the correct price list item for that order line.
