SAP deployments must work in some cases, surely.

I read somewhere that a large part of Apple's supply chain management is built on SAP, as well as being the system of record for iTunes/App Store transactions.

I can't find a reliable citation, since this will probably not be something they broadcast, due to their secrecy.

But then, they have the capital to massively spend on heavyweight internal systems.

Yes, Apple's iTunes store system of record runs on a custom SAP ABAP based system. It used to run SAP ERP but that could not take the load of transactions.

As I understand it, this is the reason why you get a weekly bill from Apple: the iTunes ABAP system makes financial postings to ERP, to reduce the overall number of transactions - and presumably also their credit card overhead.

Not sure if their SCM is SAP SCM, but the back-end of Apple is largely run by SAP software.
