• What Accounts Payable Does and Why It Matters in FIUnderstand the business and accounting purpose of Accounts Payable, how it fits within FI, and why accurate vendor liability tracking is critical to financial reporting and cash management.
• Invoice Posting, Payment Terms, and Three-Way Match with Materials ManagementExplains how vendor invoices are posted in FI, how payment terms drive cash discount and due date calculation, and how Logistics Invoice Verification reconciles purchase orders, goods receipts, and invoices before AP payment.
• Vendor Master Data and Core AP Configuration ElementsExplore how vendor master data is structured, the key configuration elements (account groups, reconciliation accounts, payment terms) that drive AP behavior, and why correct setup prevents downstream posting and payment problems.

Interview questions covered

• What payment methods are typically configured in the Automatic Payment Program for vendor payments, and what report would you use during AP month-end close to reconcile actual payment method usage against MM-driven vendor invoices?
• In a landscape where vendor advance/down payments are initiated in SAP Ariba and posted in S/4HANA using a Special GL indicator before being netted against final invoices through the Automatic Payment Program, a recent payment run resulted in duplicate payments because down payments failed to net against final invoices. As the integration architect, how would you diagnose the root cause?
• During month-end, several vendor invoices with cash discount payment terms were paid late by the AP team, but the payment run still calculated the discount. How would you investigate and correct this?
• During AP month-end close, several vendor invoices with cash discount payment terms were paid late by the treasury team, yet the payment run still calculated and applied the cash discount. How would you investigate and correct this?
• What payment methods are typically configured for vendor payments through the Automatic Payment Program, and what reports would you use during AP month-end close to reconcile actual payment method usage against MM-driven vendor invoices?
• In a landscape where vendor down payments are initiated in SAP Ariba and posted in S/4HANA with a Special GL indicator before being netted against final invoices via the Automatic Payment Program, a recent payment run resulted in duplicate payments because down payments failed to net against final invoices. As the integration architect, how would you diagnose the root cause?
• During AP month-end close, several vendor invoices with cash discount payment terms were paid after the discount deadline via the outgoing payment run, yet the discount was still applied. How would you investigate and correct this?
• Walk through how withholding tax on a cross-border vendor invoice is calculated at invoice posting versus at payment posting under Extended Withholding Tax, and explain how this interacts with the outgoing payment's bank accounting output (e.g., payment media/DME) that must carry WHT certificate information.
• Your organization is centralizing house banks into a shared service model where a single house bank serves multiple company codes for vendor payments, and supplier master records reference legacy bank keys. Post-migration, several vendor invoice payments post to the wrong GL clearing account. As the senior architect, how would you diagnose and correct this?
• Your organization is consolidating multiple house banks used for vendor payments across regional entities into a shared service center model. What master data and configuration changes are required, and what risks must be managed during the transition?
• Walk through how withholding tax is calculated and posted during vendor invoice entry under Extended Withholding Tax, and how this base amount and liability interact with the outgoing payment's bank accounting output.
• What payment methods are typically configured in the Automatic Payment Program for vendor payments, and which report would you use during month-end close to confirm the correct payment method was applied per vendor country and payment amount?
• Walk through how withholding tax base amount is determined when a vendor invoice includes both a cash discount term and a partial down payment already cleared, and how the final WHT liability posting reconciles at outgoing payment.
• How is bank determination configured in FBZP for vendor master governance, and how does this configuration integrate with the GL clearing accounts used during AP month-end close?
• Walk through the step-by-step configuration of bank determination in FBZP for automatic vendor payments, including ranking order, bank accounts, available amounts, and value date, and explain how these settings interact to select the correct house bank and GL clearing account.
• What is the role of Business Partner Grouping and its linked number range configuration when creating a Supplier in S/4HANA, and how does this determine whether the vendor account number is assigned internally or externally, and stays synchronized with the classic vendor account group used by MM?
• Walk through how withholding tax is calculated at invoice posting versus payment posting under Extended Withholding Tax, and explain how this interacts with bank accounting output during the outgoing payment run.
• From a governance perspective, how is bank determination for automatic vendor payments configured to protect the integrity of GL bank clearing accounts, and what sensitive-field controls should be in place when supplier bank details change?
• What payment methods are typically configured in the Automatic Payment Program for vendor payments, and what standard report or table would you use during AP month-end close to reconcile the total amount actually paid per payment method against the payment proposal?
• What payment methods are typically configured for vendor payments in SAP, and what reports would you use to reconcile payment method usage at month-end close?
