Via the file at helpdesk, you will often be asked to review various 855, 856, or even 850 files in order to resolve issues. 850 means purchase order, 855 means that it is a file where they either acknowledge or reject the order, and 856 is a shipping confirmation. So in this case, you would come into the DSV validation dashboard, go to order actions, put in the order number, and then look for all the different files. In this case, if we want to validate any file, you simply click on this, you download it, and then you can go to Gemini and just upload it. So remember, 856 is tracking, 855 is order acknowledgement, and 850 is purchase order. So in this case, I uploaded the 856, I asked it what the tracking number is, it actually comes back with something negative, and in this case, then we will have to escalate this to the vendor, and that can happen through Chris R.
