Organizational Units and Master Data, Project-oriented Maintenance topics were the toughest in the entire C_TS413_1909 syllabus i must say. I was like whether i would succeed in the actual S/4HANA Asset Management certification exam or not. However, one day at a time and one mock test at a time, my perspective changed and gradually i started becoming adept in these practice questions. I really liked the way mock tests are designed. It helped me gain a standing in the syllabus.
