SUPPLIER ยท BUSINESS PARTNER
How does Supplier master data work?
The central Business Partner identity becomes a usable supplier when roles add company-code and purchasing-organization data.
OBJECT ANATOMY
Separate the party from its supplier roles
BP identity
Name, address, communication, legal identifiers, tax numbers, relationships, and governed bank details describe the party.
Company code
Reconciliation account, payment terms and methods, dunning, blocks, correspondence, and withholding-tax data support AP.
Purchasing organization
Order currency, incoterms, partner functions, schema context, and purchasing blocks support procurement.
Transactions
Source records, purchase orders, invoices, payments, and partner functions consume the required supplier segment.
VALUABLE SETTINGS
Find the owner, then prove the copied value
Payment terms
Inspect company-code supplier data for AP defaults and purchasing-organization data or the PO for commercial terms. Confirm the value again on the invoice and payment proposal.
Supplier bank
Use BP payment transactions or bank details for governed bank accounts and bank keys. Bank changes require approval, fraud and duplicate checks, change evidence, and independent payment verification.
VAT and tax numbers
Legal VAT or tax registration numbers belong to central BP tax-number data. The exact categories and validations depend on country and localization.
Withholding tax
Types, codes, recipient status, exemptions, and validity normally belong to the company-code supplier extension and must agree with configuration and posting treatment.
PROOF
A populated field is not enough
Retain requester, approver, source evidence, effective date, organizational scope, change history, and the resulting PO, invoice, payment proposal, payment document, or tax posting.
