SAP is basically the core of the German compliance machine. Most of the time, people get onto SAP not because its good, but there's a bunch of compliance regs, which basically say 'use SAP'. Noncompliance results in firms basically not doing business with you.
You could try to be boneheaded and comply with whatever standards they need your own way, but that would mean your business partners would need to do more due diligence and expose themselves to risk of what happens if regulators are not happy with the way you conduct your business. So you use SAP.
