There are actually projects where the amount of development concerned is extremely large - and I know of several projects in Europe where this is the case.
For smaller (<200 users) implementations - often OneWorld is implemented in a "roughly" vanilla fashion with very little custom application development - but for those customers that implement Distribution (especially Purchasing) and Manufacturing (these customers tend toward the larger size implementations - often more than 200 users and up to 3,000 concurrent users) - there is substantial development that occurs.
I finished recently at one customer who implemented Distribution with links to Siebel and i2 (through IBM MQ series) and who rolled out 1,300 concurrent users. They run 32,000 UBE's a day at peak processing - and usually more than 20,000 UBE's a day.
They re-wrote Purchasing. Completely. Had a development staff of 10 OneWorld developers and 6 legacy developers (transitioning). They had to also write the interfaces to CRM and SCM from scratch. (one of the drawbacks of the JDE recommended "best of breed" solution from way back !) After a very difficult initial period, they have become extremely happy with OneWorld.
I can also point to other customers - some with happy stories, others with sad implementations - but believe me, once you step over a certain limit and you get out of pure Financials (which is ALWAYS implemented vanilla) - then you start seeing larger and larger impact from Development brought on from how Operations perceive the product.
Spain is a relatively new marketplace. When I was the European Launch Manager for JD Edwards SUMAH - we really did not have much exposure at all to JDE (back in 1996 - 1997). Even through to my leaving JDE in January 2000, Spain was somewhat of an unknown territory.
This was always interesting to me, especially since Latin America (Argentina and Brazil especially) and the rest of Europe were such good expansion areas for JDE.
It seems, from watching many of the posts from yourself, that Spain and Portugal are two areas that are actually growing with the OneWorld user base - which I am glad. Gives the yanks over here some food for thought when a country such as Spain has an increase in software sales throughout one of the worst recessions in living memory.
