Price going negative due to group condition
We have some item lines in order which are grouped together for Pricing group condition. i.e., what ever the price value of the group condition type, it is being shared among all the group items.
When ever we add new item lines of the same group, price of all the item lines in order which are in same group are got affected. But, we have a problem when some item lines in group are already billed.
Since some item lines in group are already billed, the price value of these items could not be changed. So, to compensate this value, the last item in group is going negative. i.e., Price of last item line in group is shown as negative (eg. -699.00).
How to avoid this scenario? Why is the price going negative?
