I've used FAS in an Oracle environment, worked in a fully DIS integrated shop (GEAC, SAP, GP, Peoplesoft and custom all in one company) and we're fully integrated with the exception of AR. In our environment, we needed the AR flexibility of a industry specialized vertical app. We have it partially integrated with GP but we still have challenges. There is no good GP option for our AR needs and we'd rather spend the money for a solid app and integration than customizations. I'd love to be a fully integrated shop but since I can't, we've erected big barriers for any non-integrated applications. Only one has made it over the hurdle.
Often I find this a company culture thing. Money and time are budgeted to add an application but nothing is included for integration. Alternatively, since integration is often a last step, integration is killed in an over-time/over-budget implementation to the long term detriment of the company. There's no one answer but I'm a little surprised at how big an issue this continues to be give that it's been a problem since the PC was invented.
