SAP cant scale worth shit, we recently added 4000 people in the call center and it took SAP 8 months to "scale" the stupid garbage pile they call software to handle it.
Then when we wanted to put in a system in the RMA database to track repair RMA data, the SAP experts said it was impossible, so one of the IT guys wrote the system we needed in PHP with a Open source SQL backend. he has a MITM box that will grab info from SAP and then spit it to the RMA server. when you do a query on the RMA page you get the full history of the device from manufacture date, to ship date, to who, to all repairs and even Tech support calls on the device.
SAP was unable to deliver this. Because SAP is really shitty.
