On some sales orders we need some parts in the workshop (to attach to the customer car) and some others need to be sent to the customer. How I need to setup the inventor, and how is the daily process to handle this case? I feel quite a lot of business have the same case. 

And the second question is, how can the mechanics remove additional parts from inventor and mount it to the customer car (e.g a delivery to workshop is made, and the parts are added to the sales order)? Best would be if they can just scan the customer or sales order QR code and then scan the parts.  Ideally, the mechanics don't need access to the sales order. They should just do an inventory operation with the barcode app.
