I am from India and now living in Netherlands. I have 2.5 years of experience in core HR and now I am thinking of giving certification exam from Belgium/ Netherlands after undergoing online training which is not from sap authorized institute.
Can I still be able to give(eligible) this SAP HCM certification?
You are eligible. You just need to get service letter from your company of your experience in order to enrol for the certification. Since you already have 2.5 years of experience, you don't need to get training from authorized training institute.
