Undo whse Item Journal


I created a Whse Item Journal to do a negative adjustment on an item (am using Directed Pick/Putaway). I registered the the Journal. Normally i would then go into Item Journal and run the Calculate Whse Adjustment. However, I actually want to cancel this WHSE Item Journal as I no longer want to do this adjustment. Is there any way that i can cancel or undo the WHSE Item Journal?
