One of our clients is running RMS 2 with the latest service packs and she has issues when modifying items in her database. Sometimes she will try to add an alias to an item but it will say the alias is already in use as an ILC or an alias for a different item. A quick query will show that it is in use, but for an item with itemid = 0. I have already deleted these aliases from the item but they keep getting re-added and the issue keeps reoccuring. Another issue she has is sometimes she will add a supplier to an item and then go to add it to a purchase order and it won't show up under the supplier. She will then check the item and the supplier link won't be there.
I have tried checking and re-indexing the database but it doesn't seem to help.
