I integrate my work systems with SAP. It's not just SAP that's a mess, I think it's a property of ERPs in general. That's because it's not code for running your business, it's code to write code for running your business. So you have two obvious problems here. First is all the shortcuts made by SAP to get something out the door to customers. Second is all the shortcuts your business used on top of SAP to get things out the door. This is a pattern that can easily create a huge mess. I've experienced this working on a product in a similar space to SAP in the past. Second thing: I don't find working with SAP too hard. One of the tricks is to work out how to keep SAP as out of scope as possible during the discovery phase using existing functionality or workarounds (that don't impact on sap as the source of truth).
