The Challenge

The Disconnect: Manual Spend Processes Hampering Your Financial Operations

Without a robust integration, managing expenses, travel, and invoices across SAP Concur and SAP ECC creates significant inefficiencies, data silos, and compliance risks. Manual processes lead to delays, errors, and a lack of real-time financial transparency.

  • Manual data entry of approved expenses and invoices into SAP ECC leads to human errors and significant time consumption.
  • Delayed financial close cycles due to slow reconciliation of Concur data with ECC's General Ledger and Accounts Payable.
  • Inconsistent master data (e.g., vendor, employee, GL account, cost center) across Concur and ECC, leading to reporting discrepancies.
  • Lack of real-time visibility into organizational spend, making budgeting and forecasting challenging.
  • Compliance risks from unstandardized processes and fragmented audit trails.
  • High operational costs associated with manual reconciliation, exception handling, and duplicate data management.

Technical Integration Details: Connecting Concur and ECC

Our iPaaS solution provides a robust, secure, and scalable framework for integrating SAP Concur with SAP ECC. It abstracts the complexity of both systems' APIs and interfaces, allowing for streamlined data synchronization and workflow automation.

Data Flow Steps

Connectors & Authentication: Establish secure connections to SAP Concur (OAuth 2.0) and SAP ECC (secure RFC, BAPIs, IDocs) using dedicated service accounts and encrypted channels.

Event Listener/Polling: Configure iPaaS to listen for Concur events (e.g., new expense report, approved invoice) via webhooks (if available) or efficient polling mechanisms with change detection.

Data Retrieval: Upon trigger, iPaaS calls relevant Concur APIs to fetch data (e.g., `/v3.0/expense/reports`, `/v3.0/invoice/invoices`).

Data Mapping & Transformation: Use the iPaaS's visual designer to map Concur fields to SAP ECC fields. Apply AI-assisted transformations, lookups (e.g., GL accounts, cost centers from ECC cache), and business rules.

Data Validation: Implement pre-posting validation checks on the iPaaS to ensure data conforms to SAP ECC's requirements, leveraging AI for anomaly detection.

ECC Data Posting: Invoke appropriate SAP ECC BAPIs (e.g., `BAPIACCDOCUMENTPOST`, `BAPICUSTOMER_CREATEFROMDATA1`) or send IDocs (`INVOIC02`) to create or update records.

Error Handling & Monitoring: Log all transactions, implement retry mechanisms for transient errors, and trigger alerts for persistent issues. Provide a centralized dashboard for end-to-end visibility.

Status Update (Optional): Update Concur with status from ECC (e.g., payment confirmation) via Concur APIs.

Data Touchpoints

SAP Concur: Expense Report, Expense Entry, Receipt, User/Employee, Vendor/Supplier, Invoice, Payment Transaction, Company Card Transaction, Cost Center, GL Account, Approval Workflow, Policy Rule.
SAP ECC: General Ledger Account, Vendor Master, Employee Master, Cost Center, Invoice (FI/MM), Financial Document (BKPF/BSEG), Payment Document.

Automated Expense Report to GL Posting

Streamlines the entire expense report lifecycle, from employee submission in Concur to automatic posting in SAP ECC's General Ledger, ensuring timely reimbursement and accurate financial records.

Integration Steps:

  1. 0 Employee submits expense report in SAP Concur.
  2. 1 Concur routes for approval based on policy rules and organizational hierarchy.
  3. 2 Upon final approval in Concur, an event trigger is sent to the iPaaS.
  4. 3 iPaaS retrieves the approved Expense Report and its Expense Entries from Concur (`/v3.0/expense/reports`, `/v3.0/expense/entries`).
  5. 4 Data is transformed, mapping Concur Expense Types and Cost Centers to SAP ECC GL Accounts and Cost Centers.
  6. 5 iPaaS uses `BAPIACCDOCUMENT_POST` to create financial documents (GL entries) in SAP ECC.
  7. 6 Payment status (e.g., reimbursement) is synchronized back to Concur from ECC.

Business Outcome

Faster employee reimbursements, accurate and timely GL postings, reduced manual data entry and reconciliation, enhanced compliance.

Technical Documentation

API Endpoints & Data Logic

Technical details for developers and architects.

Method Endpoint Purpose
GET, POST, PUT /v3.0/expense/reports Retrieve, create, or update expense reports and their statuses. Crucial for posting approved reports to ECC.
GET, POST, PUT /v3.0/expense/entries Manage individual expense entries within reports, including details and attachments. Used for detailed GL postings.
GET, POST, PUT /v3.0/invoice/invoices Access and manage vendor invoices, including creation, approval status, and line items. Essential for AP automation.
GET, POST, PUT /v3.0/common/users Provision and manage user profiles, including employee details, roles, and permissions. Used for HRIS sync.
GET, POST, PUT /v3.0/common/vendors Synchronize and manage vendor master data for invoice processing. Used for bi-directional vendor sync.
POST /v3.0/financial/glentries Post general ledger entries for approved expenses and invoices. (Direct GL posting, less common than `BAPIACCDOCUMENT_POST` from iPaaS to ECC).

⚡ Transformation Logic

  • GL Account Mapping: Conditional logic mapping Concur `ExpenseType` to `SAKNR` (ECC GL Account). Example: `IF ExpenseType = 'Meals' THEN SAKNR = '471100' ELSE IF ExpenseType = 'Travel' THEN SAKNR = '400000'`.
  • Cost Center Derivation: Lookup `KOSTL` in ECC based on `EmployeeID` or `DepartmentID` from Concur.
  • Company Code Derivation: Determine `BUKRS` based on the `CostCenter` or `EmployeeID`'s organizational assignment in ECC.
  • Vendor Harmonization: Match Concur `VendorName` and `Address` to existing ECC `Vendor Master` (`LIFNR`). For new vendors, trigger ECC vendor creation.
  • Currency Conversion: Convert amounts to ECC's company code currency if different, using real-time exchange rates from a configured source.
  • Date Formatting: Standardize date formats (e.g., YYYYMMDD for ECC BAPIs).

🛡️ Error Handling

  • Invalid GL Account: Concur `ExpenseType` maps to a non-existent or inactive `SAKNR` in ECC. (Solution: Alert, route to finance for mapping correction).
  • Vendor Not Found: Concur invoice `VendorID` cannot be matched to an ECC `LIFNR`. (Solution: Alert, route to AP for vendor master creation/reconciliation).
  • ECC System Unavailable: Temporary network issue or ECC server down. (Solution: Automatic retry with exponential backoff, then alert if persistent).
  • BAPI Authorization Error: Integration user lacks permissions for `BAPIACCDOCUMENT_POST`. (Solution: Alert, security team intervention).
  • Data Policy Violation: AI detects a transaction exceeding policy limits not caught by Concur. (Solution: Flag for review, prevent ECC posting).

Frequently Asked Questions

Common questions about integration implementation, security, and best practices.

General Integration FAQs

▸ Why is a modern iPaaS essential for SAP Concur and SAP ECC integration?
A modern iPaaS (Integration Platform as a Service) moves beyond simple point-to-point connections, offering a centralized hub for all Concur-ECC integrations. It provides robust capabilities for data mapping, workflow orchestration, API management, error handling, security, and scalability, essential for complex enterprise environments. This ensures resilient, auditable, and efficient data flow between Concur's spend management and ECC's financial core.

AI & Automation FAQs

▸ How does AI enhance SAP Concur and SAP ECC integration workflows?
AI significantly augments Concur-ECC workflows by automating tasks like intelligent GL account mapping based on expense types and vendors, performing real-time policy compliance checks, detecting anomalies or potential fraud in spending patterns, and suggesting solutions for integration errors. This reduces manual effort, improves data accuracy, and provides proactive insights for better spend management and financial control.

Low-Code/No-Code FAQs

▸ What are the benefits of low-code/no-code for Concur and ECC integrations?
Low-code/no-code tools empower finance and operations teams to build and modify Concur-ECC workflows without extensive coding. This accelerates development cycles, reduces reliance on IT, and allows business users to quickly adapt automation to changing policies or operational needs, such as custom approval routing, data validation rules, or new GL account mappings. It fosters agility and business ownership of integration processes.

Specific Workflows FAQs

▸ How do you handle corporate credit card transaction reconciliation with Concur and ECC?
We automate this process by integrating with corporate card providers to import daily transaction feeds into Concur. The iPaaS then facilitates intelligent matching of these transactions with employee-submitted receipts and expense entries within Concur. Upon approval, the reconciled data is transformed and posted to the appropriate GL accounts in SAP ECC via `BAPIACCDOCUMENT_POST`, ensuring accurate reconciliation and reducing manual effort for finance teams.
▸ Can I integrate SAP Concur with my existing SAP ECC for vendor invoice processing?
Absolutely. Our solution provides end-to-end automation for vendor invoices. Invoices are processed and approved in Concur Invoice, and upon final approval, the iPaaS transforms and posts them to SAP ECC's Accounts Payable module. This can be done via `BAPIACCDOCUMENT_POST` for direct financial postings or `IDoc INVOIC02` for integration with Materials Management (MM) invoice verification, ensuring seamless vendor payment initiation.

Security & Compliance FAQs

▸ What are the key security considerations for Concur-ECC integrations?
Key considerations include using OAuth 2.0 for secure Concur authentication, encrypting all data in transit (TLS 1.2+) and at rest, implementing the principle of least privilege for integration user accounts in both systems, and maintaining comprehensive audit trails. For SAP ECC, this means dedicated service accounts with specific authorization objects and secure connectivity (e.g., VPN, private link) for on-premise instances. Adherence to compliance standards like SOC 2, GDPR, and SOX is also crucial.

Performance FAQs

▸ How do you manage Concur API rate limits and SAP ECC performance for high-volume integrations?
For Concur, we implement intelligent batching of requests, queuing mechanisms, and parallel processing within the iPaaS to efficiently utilize APIs while respecting rate limits. For SAP ECC, we leverage its optimized BAPIs/IDocs, employ asynchronous messaging, and implement throttling within the iPaaS to prevent overwhelming the ERP. Caching of master data and pre-validation on the iPaaS side also significantly reduces load on ECC, ensuring high throughput and system stability.
