We are doing study on 10.1 with Service Catalog module turned on. We noticed that when adding the service to the cart, before ordering it, you cannot easily add attachment to the order. You would have to go to the other module (Order Management) and then find your un-submitted requisition and then add the attachment. This is very user unfriendly. In older versions (My Services module), you would have Add & Review Order button where you could add attachment.
Does anyone know if there is an easy way to add attachment to the order in Service Catalog module?
We have also come across this issue, unfortunately there is no 'Add and Review' button anymore which is what allowed one to do this in the past. It seems attachments cannot be added until a requisition exists for that request (i.e. a valid requisition number exists).
There were some small changes we did to make the flow a little simpler though, we modified the order confirmation page to included a hyper link to navigate back to the request without having to go back to ongoing orders, this was done by modifying the handlebar templates and scripts so it can be a complex change.
