When a picking route line is split into a number of other lines (whether this is manually split or the system splits when different batches are reserved) each of these split lines still retains the LOT ID as that of the sales line level. 

 This can cause problems when a customer is using an interface with a 3rd part warehouse to pick those picking lines. There is no way to differentiate between which of the lines has been picked and which have not.

 Is there a way that each picking line on the picking route can be uniquely identified?

 Is Microsoft looking into a resolution for this in future releases?

 Can each split line create a separate picking route?
