I am planning to take up the 1909 certification and for the same I have taken a learning hub access as well. But I am not sure if I am preparing the right way. There are 2 courses available with same certification code. 'SAP S4-HANA Manufacturing' and 'SAP S4-HANA Manufacturing-Upskilling for SAP ERP Experts'. Do I need to prepare for both. Inside them has set of courses S4H00,S4200....etc. Is just reading then enough or anything else I need to do? It will be very helpful if anyone can guide me.
