Which course is the best for a better career in HR, Six sigma, or SAP? And from where I can get this training?

Hello, I am an HR working in an IT company, for career growth I am looking for the best HR certification course. Can anyone help me with this?
Firstly I need to know that is there any course for HR in Six sigma?
If yes, then which course is the best for a better career in HR, Six sigma, or SAP? And from where I can get this training?
Please guide me. Thanks in advance.

SAP is much more useful as it offers an integrated database for taking many employee-centric decisions. Six Sigma improves the process and it helps more in quantifiable operations like quality control, manufacturing activities, etc. SAP has multi-functional applications like Materials, sales, production planning, etc.
