I have decided to write SAP Central Finance in SAP S/4HANA certification exam however I was not prepared as per syllabus defined. I decided to take up erpprep.com online practice exams for SAP and I like the way questions are formed fit for syllabus. I finally scored 88% in SAP S/4HANA Central Finance exam yesterday. I recommend SAP candidates to go with this site to improve confidence and understanding of exam.
