EWM - Packing Outbound Del using code

HI All,

I need to do packing for outbound Del using custom development. I checked standard TCODE where REPACK method is used . Also, below thread explains the same : My concern is I have only 1 HU so what it would - in below method :

Source HU or Dest HU. Also, from where I should bring another HU:

I got below blog as well but it uses another method . I tried with source and dest HU as same HU which is created at runtime but it did not work.

Thanks !!
