Those two sentences seem to contradict one another. How does not STOing first qualify as using Subt correctly and what then is the incorrect usage? When you Subt something from a location that it is not located in you are giving the system all the information it needs to make a decision on whether that item was accurately located or not in exactly the same way it can determine a baffle error while pulling a batch. It now knows the DPCI of the item you are subtracting, the location you are subtracting it from, and whether it was located there a second ago. The two reasons I believe that to be true are 1) I read that a baffle error will be caused by using Subt without STOing it first in the "resetting the accumulator" guide and 2) the logic of it makes perfect sense to me. I'm not trying to argue with you but please help me understand why you believe that this information would be ignored by the system.
I'd love to be wrong! Help me see where I'm off track.
He is correct. For whatever reason errors are only detected in generated batches. The only down side to not STOing first is SUBT will not detect clearance. I however find that to be a fair trade off for the time saved not STOing first. You can in fact test this theory by SUBTing 9999 without STO an item from a fill group you do not normally see into a Z location. Then check the next weeks DTK report for a error in the fill group in that area. I think many of us have tried this and gotten the same results, no error.
