Sales Return through mobile device for delivered Quantity not invoiced

Version : AX 7 Release- Update 2

Hi, 

We are using complete WMS process in AX7, all our warehouses are WMS Enabled. 

Scenario:

 Now, we want to create a Sales Return process for the delivered Quantity. Invoice is not done.

i.e Sales Return with negative line will be created in the same sales order, and the expectation is

1.  Work should be created for the negative line

2. Warehouse workers should be able to Register the item for the sales return.

3. Shipment should be confirmed

4. Delivery note should  be posted for negative lines.

We want to know whether the above steps are possible.
