Hi Mrinal,
Stock gets released when picking is cancelled , but then it needs to be put back in its correct place. There are 3 options
1. Just release stock : Manual WT needed for put back
2. Release stock + Create WT in foreground
3. Release stock + Create WT in background
Putback WPT is considered from EWM-GI - Cancel pick - Define WH number control for putback
With regards,
Mrinal
