  3. C Convert all customers and vendors to business partners.
  4. D Update all custom code that calls customer master transactions.

Correct Answer

C — Convert all customers and vendors to business partners.

Explanation

Why Business Partner Conversion Is Required

Traditional SAP ERP uses separate customer master and vendor master object models. In SAP S/4HANA, the mandatory target approach is the Business Partner model supported by Customer-Vendor Integration (CVI).

Therefore, customer and vendor data must be converted into the Business Partner format as part of the migration to SAP S/4HANA.

Core migration principle: Consolidate the former customer and vendor master records into the unified Business Partner data model before or during the S/4HANA conversion process.

Migration Workflow

Steps to Convert Customer and Vendor Data

  1. Determine the conversion scope Decide whether all customer and vendor records or only a defined subset will be migrated to SAP S/4HANA.
  2. Analyze the current data Review customer and vendor information for completeness and accuracy, and identify missing or incorrect records that require correction.
  3. Perform data cleansing Remove duplicates, resolve data-quality issues, and standardize records to support a smoother migration.
  4. Map the source data Match fields in the existing customer and vendor masters to the corresponding fields in the SAP S/4HANA Business Partner model.
  5. Convert the data Use SAP migration tools to transform customer and vendor records into the Business Partner format accurately and efficiently.
  6. Test and validate Run test scenarios to confirm that the converted records are complete, correct, and working as expected in SAP S/4HANA.
