The "Apply each order qty" option can now be calculated from the care order's original OrderQty instead of its RemainingQty. With "Apply each order qty" = 10% and a care order of OrderQty=100 / ExecQty=10, the new option sends 10 to market (based on the original 100) rather than 9 (based on the remaining 90). The existing RemainingQty-based behavior is retained as an option. (Ref 218655) |
