SAP offers about 25 modules and that could lead to confusion as to which module is the easiest. If the question pertains to getting a job, most recruiters look for experience. and do not like taking the risk of entrusting such important work to fresh candidates.
The most popular first level entry to the
SAP HANA course is the Basis i.e. the (SAP System Administration) and SAP ABAP Programming specialties. These are the most pursued courses immediately upon graduation. The two specialties are ideal for the candidates with computer science or similar background.
For candidates that do not have a computer-related background, could consider the SAP SD (Sales and Development) or SAP MM( Material Marketing) or SAP FI ( Financial Accounting). Like mentioned earlier, it boils to an individual’s interests and skills.
