Hi again Melissa, I'm not sure which section you are referring to? Is it that having to do with data replication regarding real time reporting? If so we are talking about the Logistics Information System or LIS. The way this works is as following. The company defines what details of their business they need reporting on. The reporting option is offered as an optional feature to most R/3 transactions. Anyway, the transaction then writes out that statistic into its dedicated reporting table. (Not all the surrounding data, just that one statistic) So in essence, yes there is a data column that is replicated somewhere in some reporting table. NOW the whole idea here is to not touch the original applications table again. If you did the people running the reporting start stepping on the people trying to place sales orders and that is what SAP does not want. Note that this replicated data column does not hang around for ever. The data is eventually condensed more and more depending on the customers desires and, I believe, archived independently. The downside is the one-time double write of fresh data that needs to happen in the first place and this is may be critical depending on how complex the reporting requirements are. It seems IBM's are very complex and they want to offload these stats to another system to be processed. This way, CPU cycles are not stolen from the online users. I don't blame them. I had a customer once who was getting killed by this reporting tool and it turned out to be a bunch of clowns from sales who were looking up what kinds of sales commissions they were going to be getting every time that made a sale. (Bunch of greedy b**tards, all of them!!!). Hope this helps, J
