How to start in ABAP
Hi!
Because there are many questions on this topic, please let me share my tips on how to start with ABAP.
Create an SAP BTP trial account and learn RAP.
Create an SAP BTP trial account and learn RAP. For example, you can follow the following tutorial:
https://developers.sap.com/tutorials/abap-environment-rap100-generate-ui-service?from=build-an-sap-fiori-elements-app-using-the-abap-restful-application-programming-model-rap-beginner-rap100Not necessarily, but it is very good to have hands-on experience in a non-cloud ABAP system because, to be honest, cloud projects are rarer than classical on-premise projects.
There are two possibilities to get acquainted with non-cloud ABAP programming:
* Install S/4 HANA 1909 in Docker:
https://github.com/jenizar/sap-s4hana-1909-on-docker
Note: You need suitable hardware
* Install ABAP Trial 7.52 if you have weaker hardware.
Note: RAP is not working there (but you can learn it in SAP BTP Trial)
- Find sites such as "30 ABAP interview questions," etc., and go through all the questions you still don't know. Use your ABAP Trial and hosted ABAP systems to test them (from items 1 and 2).
If you have the possibility to get a starter position without experience, don't wait, because real experience is much more valuable than any tutorials.
For example, many tasks in real projects are:
* "Please tell me why it does not work, or why this amount is 100 instead of 80. Where does it come from?" And you debug it...
* "Please add one column to the existing report or integration." And you need to review tons of legacy code.
I don't know how to train for these situations unless you are on a real job. So get hands-on experience as fast as possible.
