If an item was added to transaction by scanning lookupcode, I can delete that item from custom component successfully. When an item is added using '+' key, I'm able to delete that entry but later it fails somewhere in Store Operations code. It throws a message that object variable is not set to an instance and it crashes.
I have tried same thing by putting zero quantity instead of deleting entry, so that it will give a default system a chance to remove this item from transaction. It does delete it by detecting that it has zero quantity but later fails with same message.
any idea what they are doing?
