In the first echelon, the diamond partners awarded by SAP include: IBM Consulting, Deloitte, Yin Zhi, Capgemini, Capgemini, Huawei (as the exclusive server manufacturer), Pactera, Tata and so on.
The second echelon is almost some domestic big-name software companies such as Neusoft and Digital China.
There are the third echelon and the rest, but some of them are often supported by SAP, which is better, such as Haitong Anheng and Qixing.
I can only say hehe for the rest.
