Hi Eike,
NWBC is for net weaver business client which need to active the SICF transaction. As you mentioned we use /scwm/rfui as well.
Regarding to your question: For the putaway of the materials in production supply area:
Do you use the transaction code /SCWM/STAGE for production supply? It can be used as job for creation of warehouse task.
best regards,
Liyu
