Posting Capabilities
ERP System
SAP
Live Payment Posting
Payment Layer
PaymentHub
FI Document Posting (Incoming Payments)
Payments create FI documents in SAP with proper posting keys, customer clearing, house bank assignment, and cost center/profit center allocation per SAP accounting principles
Outgoing Payment Run
AP payment proposals processed through PaymentHub create FI documents for outgoing payments with vendor clearing, payment method assignment, and bank determination
GL Account Postings
Fee accruals, surcharge collections, and reconciliation adjustments post as GL account documents with proper cost element and profit center assignment
Customer Open Items
Open customer line items, payment terms, dunning levels, and credit exposure data sync from SAP FI-AR to the customer portal and AR workflow engine
Bank Statement Reconciliation
Gateway settlement data maps to SAP electronic bank statement format for automated clearing of open items in the bank reconciliation sub-ledger
Common Edge Cases & Special Handling
Customization Points
BTP Extension for S/4HANA
Deploy custom posting logic as SAP Business Technology Platform extensions that execute before PaymentHub FI document creation. Extensions can enrich posting data with additional SAP fields, apply custom validation rules, or trigger SAP workflows upon payment receipt.
DI API Hook for Business One
Insert custom logic into the Business One DI API posting flow for custom field population, user-defined field assignment, or business partner update triggers. Hooks are maintained outside the core connector and survive version updates.
Cost Object Assignment Engine
Configure rules that assign cost centers, profit centers, WBS elements, or internal orders to payment postings based on transaction attributes. Rules support hierarchical fallback logic — customer-level override, customer group default, company code default.
House Bank Determination Override
Override SAP's default house bank and account determination for payment postings based on payment method, amount threshold, currency, or entity. Useful for routing high-value payments to specific bank accounts or directing ACH settlements to separate house banks.
AI Copilot for SAP Integration
PaymentHub's AI Copilot automates GL mapping, test transactions, and fee analysis for your SAP integration.
S/4HANA Configuration Analyzer
Reads your S/4HANA customizing tables — company codes, chart of accounts, cost elements, profit centers, house banks, and payment method configuration — and generates complete posting templates. Validates every organizational assignment combination against S/4HANA configuration rules.
FI Document Test Suite
Generates FI document test scenarios covering standard payments, cash discount scenarios, partial payments, credit memo clearing, and multi-company-code postings. Executes each against S/4HANA sandbox and validates posted documents against expected FI line items.
Bank Statement Format Mapper
Analyzes your SAP electronic bank statement configuration and maps PaymentHub gateway settlement data to the expected format. Generates test bank statements and validates automated clearing rules, ensuring settlement data flows into SAP bank reconciliation without manual formatting.
Security & Compliance
SAP BTP OAuth 2.0 authentication with X.509 client certificates for S/4HANA cloud; SAP GUI service user for on-premises
Business One Service Layer authentication with session-based tokens and company database isolation
TLS 1.2+ encryption for all RFC, OData, and REST communication with SAP endpoints
SAP authorization object validation — PaymentHub respects S/4HANA authorization groups, activity permissions, and company code restrictions
Integration Setup
Configure SAP connectivity — BTP destination for S/4HANA cloud, RFC connection for on-premises, or Service Layer credentials for Business One
Run AI copilot S/4HANA configuration analysis to generate posting templates from customizing tables — company codes, charts of accounts, cost centers, and house banks
Review and approve organizational mapping, cost object assignment rules, and tax code determination logic
Configure payment method mapping, cash discount handling, and house bank determination rules
Execute FI document test suite across all company codes and payment scenarios, validating posted documents in SAP
Configure customer portal with SAP open item sync, then deploy to production with monitoring and exception alerting
AI Copilot accelerates this setup
With AI Copilot enabled, GL mapping and test transactions are handled automatically using your SAP schema. Most teams complete the full setup without writing any configuration code.
