RL and RLL Delivery type

Hi All,

In other threads, I have seen that the delivery  type RL is used in Movement type 161 ( Returns to Vendor with reference to a Purchase Order )

and delivery type RLL is used in movement type 122 ( Return delivery to Vendor without reference to PO ).

But how does one create a delivery with a 122 movement type ? I thought that if we use MIGO Return Delivery and refer the Goods Receipt material document (101 movement type), the stock gets reduced automatically from our location. There is no delivery being created here. Is there a way to create a delivery using 122 movement type ? If so, how is it to be done ?
