To use RFC HU_GET_RFC_DATA from your own ABAP’s, there are two steps.
- If you have defined packing station profiles in customizing (transaction HUPAST_C), you can use the function module read_packstation to determine the profile based on the hostname of the user’s PC.
- Use the RFC call HU_GET_RFC_DATA in conjunction with ERP-Scale to determine the current weight from the serial device
Note: You can use the packing station profile with ERP-Scale even if you have not activated handling unit management in SAP.

Determine Packing station profile based on hostname of user’s PC when using Fiori.
If the code is being used in a Fiori app, the function module TH_USER_INFO does not return the hostname of the operator’s PC, but the IP address. The FQDN of the operator’s PC can be determined using function module RFC_IP_TO_HOST.
We suggest creating a second packing station profile with the terminal matching the RFCHOST returned by RFC_IP_TO_HOST. This way the custom transaction will determine a valid packing station profile if called from the SAP gui or Fiori.
