Problem is that many companies when starting SAP implementation ending up building their own ERP on top of SAP. And that is ridiculous waste of money. From my experience that is mostly due to internal company politics and lack of IT management skills.

Just one example : we had a big implementation in the big region where Implementation manager for SAP introduction was originally from. He was approached by some factory director and asked if we could change the standard process as "You know we have these guys working for years and they are not very adaptive for changes..let's make it easier for them, will ya?" And Implementation manager agreed. "As ERPs come and go, but connections and people stay there". So it took 3 consultants + 2 developers three months to rework the process. It later was not working perfectly, so many bugs and enhancements(as these guys couldn't stop asking for more changes) caused more money spent in support.. And it's just one episode in several years long implementation cycles.

On other hand I had very smooth implementation in TOP 50 company. But for them it was not only to implement as software, but also to audit their internal processes and to eliminate waste. There dedicated Implementation Manager started introduction to SAP with words: "We are Columbus, SAP is as ship which will bring us to America. And wont be easy, but I hope you will all jump on this ship otherwise we will have to leave you..".

SAP ERP is made for standardizing and simplifying processes, so just don't invent light-bulb every time you need a light in a room.
