SAP Business Partner

Customer 4711 and vendor 4711 are the same supplier — who is also a buyer. In classic SAP ECC, those are two master records in two tables with two number ranges. Duplicate maintenance, inconsistencies, reconciliation effort. The SAP Business Partner ends this separation.

One master record for all roles

The Business Partner (BP) is the single object for business partners in S/4HANA. Customer, vendor, contact person, prospect — all are roles of the same BP. The old transactions XD01/XK01 are gone, the tables KNA1 and LFA1 exist only as compatibility views.

What this means in practice: a company with 50,000 customers and 20,000 vendors must merge them before the S/4HANA migration. Identify duplicates, harmonize number ranges, adjust authorizations. This is mandatory, not optional.

Migration: the underestimated task

SAP provides the Customer-Vendor Integration (CVI) as a migration tool. In theory, an automated process. In practice: 10-15% of master records require manual rework — missing fields, duplicate addresses, orphaned assignments.

This is where AI steps in: matching algorithms identify duplicates via fuzzy name and address comparisons with hit rates above 95%. We use this in our SAP migration projects to reduce manual rework by up to 60%. Master data quality is not a glamorous topic — but it determines the success of every S/4HANA conversion.
