How to re-use of handling unit number (SSCC)?
We are implementing handling unit management to our customer and HU number is SSCC code. The inbound process intended to use is as follows:
1. Create purchase order with confirmation control key 0004 (shipping notification) and receiving storage location is a HU-managed storage location.
2. Create inbound delivery against the purchaser order via VL31N.
3. Pack HU in the inbound delivery and then post goods receipt.
Further, our customer is using fix SSCC on each pallet physically, so we will maintain external HU number range in SAP accordingly, but the issue is, how to re-use of the SSCC in the inbound process? Currently, once the HU (SSCC) is received in SAP, the system status will be PHEX and WHSE, then next time when the pallet is empty physically, we still cannot re-use of the HU (SSCC) in the inbound delivery for GR process in SAP.
Can anyone of you give me some suggestions how to re-use of handling unit (SSCC) in SAP?
Thanks in advance.
