Custom Code Readiness Checklist for S/4HANA 2023 with Sachin Artani

Every ABAP developer on an ECC to S/4HANA migration project hits the same wall - you know something needs to change in your code, but you don't know where to look it up, which tool to use first, or in what order to do things.

This is a curated set of official SAP documents, hands-on video walkthroughs, and community resources - handpicked and ordered so you don't waste time hunting. Want to know which ATC checks to run before migration? It's here. Need to see how a classic SEGW OData service gets migrated to a RAP-based OData V4 service, step by step? It's here. Looking for where to find the right replacement for a deprecated BAPI or user exit? It's here too.

No fluff, no PDF rabbit holes. Just the right resources, in the right order, for the developer doing the actual work.
