Hi, I wanted to ask the community about an opinion regarding the way order item cancellation and update are currently implemented.
There are differences between these two processes. Order update: Shopping cart is recreated from the order, then appropriate changes are made and the cart is stored again. Order item cancellation is implemented in shorter way, that IMO is little bit incorrect. For example if you cancel only part of an order item, then all corresponding item adjustments(tax, promotion) are not recalculated. They are created balancing order header adjustments for the difference between the previous and new order adjustment amounts. In this thread was proposed not to create balancing adjustments when cancelling order items: http://markmail.org/message/3yv6etafkqo6fuu2 I think that this shorter implementation was considered and implemented because of the problem with inventory reservations, but IMO in the current implementation inventory reservations are not created in a right way also. E.g if you create order that include promotional order items during order item cancellation all promotional order items are cancelled(with their inventory reservation) and the system creates new promotional items if applicable. In many situations they are created unique promotional items, but with new inventory reservations. I will be very glad if someone can confirm that and propose an idea how these processes(order items cancellation and update) should be implemented in a proper way. Regards, Rashko Rejmer
