Start with a business process
If you enjoy sales operations, map an order through delivery and billing with SAP SD. If you prefer procurement, follow a purchase from requisition to goods receipt in SAP MM. Finance learners can start with SAP FICO and see how those transactions reach the general ledger.
Choose technical training if you want to build
Start with ABAP programming and debugging. Move into RAP when you can model data in CDS. For side-by-side extensions, learn BTP foundations before CAP.
Compare the practical work
Ask which scenarios you can practise, what environment the batch uses, and what experience the training assumes.
