About S/4HANA Table Migration
When migrating from SAP ECC to S/4HANA, many database tables undergo significant changes. The most impactful change is the introduction of the Universal Journal (ACDOCA), which replaces dozens of FI and CO tables (BSEG, GLT0, FAGLFLEXA, COEP, and more). In Sales & Distribution, status tables like VBUP and VBUK are merged into their parent tables (VBAP/VBAK). The Business Partner (BUT000) replaces separate customer (KNA1) and vendor (LFA1) master records.
This migration guide helps SAP developers and consultants identify which tables change and find their S/4HANA successors. Each table links to its detailed CDSee page with fields, CDS views, and lineage information.
