If you see SAP’s guidelines, they have replaced SAP FICO with SAP S4HANA Finance. So essentially, SAP FICO is an obsolete module currently.
SAP has offered 2 kinds of courses for the Finance module. One is SAP S4HANA Finance Associate, and the other is SAP S4HANA Finance Professional.
So, people who don't have previous knowledge or expertise in SAP Finance or FICO, they can opt for the Associate program. Those who are already operating as SAP adviser, they can upgrade themselves with Professional level program.
However, technically, you can learn SAP FICO too, instead of choosing the Associate level program before doing SAP S4HANA Finance or what it is popularly called SAP S4HANA Simple Finance.
This means, clearly you wish the base-level knowledge of SAP Finance before entering into S4HANA Finance. So SAP FICO is the cheapest and good option for the same.
Thus, it is advisable to first Learn SAP FICO (available for free on Youtube).
Post FICO, choose SAP S4HANA Finance coaching to be an expert consultant.
