I've never seen this before, but we have seen it 5 times today. Basically we are doing physical inventory for the entire store. We have about 7 departments and 120 categories. We are using 2 workstations with each one entering results from different categories. What's happening is while entering inventory for one category the contents are REPLACED with the entries from another category. We're a bike shop and the category doing the replacing is our bike inventory that we counted first. I have since deleted this inventory, but it is still doing it. It's always the bike inventory that replaces whatever we are actually counting. Bikes are unique in that they are serialized, but nothing was odd during their inventory. This is about the 20th time we have done a physical inventory and have never seen it before.
It's quite odd. You are working on a category entering in 100-500 or so items, everything is looking good. You have calculated it a few times, recounted it a few times, open and closed it a few times; then all of a sudden you open it and it's no longer gloves, but full of bikes. And you have to start over. Very weird.
We are careful only to open the each physical inventory on a single computer, and I have reindexed, and restarted the system. But it is still occuring. At this point I don't think we can continue doing inventory until we figure out what's up.
Any ideas?
