On the ASN HU screen one can pack ASN items into handling units. This can be done manually or automatically (if a packaging specification has been defined -> Packaging Specification).

The actual packaging is done in the EWM. So the HU screen uses EWM function modules, here (i.e. /SCWM/HU_PROPOSAL).

Between the HU UI and the EWM there is an assistance class (/SCA/CL_PACKSPEC_HDLR) that communicates directly with the EWM. This handler class is used on the packaging specification screens as well.
