How to Do Pallet Packing in SAP ECC (Nesting an Outer Box HU into a Pallet HU)
Question
I need to pack an already-built outer box (a lower-level Handling Unit) onto a pallet HU in SAP ECC using standard function modules. What’s the correct sequence, and how do I build the packing request so the box gets nested inside the pallet? Below is the approach I used.
Answer
The concept here is HU nesting — like Russian nesting dolls: the product sits in a box, and that box (the outer box HU) sits on a pallet (the pallet HU). This routine performs one nesting step: placing the outer box into the pallet.
The key is to follow the standard sequence in order — Refresh → Get/Lock HUs → Pack → Post. Skipping any step (especially the refresh or the lock) is the usual cause of packing that “works once then silently fails.”
Building the packing request (
ls_pack_req):venum/exidv→ the target pallet HU (what you pack into)sub_hu_venum/sub_hu_exidv→ the content outer box HU (what gets packed)pagew→ weight,veanz = 1→ one unit,velin = 3→ item category for HU-in-HU (packing a whole HU, not loose material)The four SAP standard function modules used:
HU_PACKING_REFRESHHU_GET_HUSHU_PACKING_AND_UNPACKINGHU_POST(if_commit = 'X')After each call,
sy-subrcis checked. On failure, the SAP message is captured into the status field and the routine exits; on success, the record is stamped with status, date, time, and user.Code
