Packing with Cartonization Planning 
In packing with cartonization planning, the system uses the PSHUs as templates for proposing packaging materials or destination HUs for shipping HUs while packing at the work center or using radio frequency (RF).
You have implemented the Business Add-In BAdI: Destination HUs and Packaging Materials from PSHUs or use the default implementation.
For more information, see Customizing for Extended Warehouse Management under .
The destination HUs or packaging materials proposed by the system depend on the implementation of the BAdI: Destination HUs and Packaging Materials from PSHUs. The default implementation /SCWM/ESI_WRKC_UI_POHU aims at emptying the pick-HUs as soon as possible. You can also implement the BAdI in a way that the shipping HUs become completely packed as soon as possible.
