I have only been exposed to SAP a long, long while ago, but back then it was leaps and bounds better than the two ERP systems the company had used previously. If you think SAP is a nightmare, these other systems would probably drive you clinically insane. One system had three completely different, supposedly equivalent, client UIs. Each was equally undiscoverable, and had its own set of arcane, non-standard and inconsistent UI conventions that was completely different fron the other clients. So even if you knew how to enter a certain record in one client, your knowledge was almost wntirely useless with confronted with one of the other two. I am not even getting started on the server implementation and the myriad of bugs in the system.
