Did you look at your appreciation first and see if anything jumps out at you? I usually have a part's update that I overrode the cost/qty (Freon, pag oil, dexos etc) where the qty stays the same but the cost updates to the bulk amount.
If that doesn't help I look at my Annual Activity & Benchmark trend report in DSDA to see which sources jumped. I've had some key punch errors that were fairly easy to locate once I knew which source I needed to look at.
