The Challenge

The Challenge: Disconnected ERPs & Operational Inefficiencies

Running Epicor E9 and SAP S/4HANA in isolation creates significant operational friction and limits strategic agility. Manual data transfer, reconciliation efforts, and delayed information flow lead to costly errors, missed opportunities, and a fragmented view of your business.

  • Data Silos & Inconsistency: Critical information (customer, product, financial) remains trapped in separate systems, leading to conflicting data and a lack of a single source of truth.
  • Manual Processes & Human Error: Tedious data entry and reconciliation between E9 and S/4HANA consume valuable time, introduce errors, and slow down critical business cycles.
  • Delayed Reporting & Decision-Making: Financial data aggregation and operational insights are hampered by batch processing and a lack of real-time visibility, impacting strategic planning.
  • Fragmented Customer & Supply Chain View: Inconsistent customer records and outdated inventory levels lead to poor customer experiences and inefficient supply chain management.
  • Compliance & Audit Risks: Manual interventions and disparate data sources complicate audit trails and increase the risk of non-compliance with financial regulations.

Technical Integration Architecture & Data Flow

Our iPaaS provides a robust, API-first approach to connect Epicor E9 and SAP S/4HANA. It acts as a central nervous system, orchestrating data exchange, transformations, and business logic, ensuring secure and scalable communication between these critical ERP platforms.

Data Flow Steps

Event Trigger/Polling: An event occurs in either Epicor E9 (e.g., new sales order, inventory change via Service Connect or custom API) or SAP S/4HANA (e.g., new Business Partner, material update via OData API or Event Mesh). The iPaaS either listens for these events via webhooks/API calls or performs scheduled polling for less time-sensitive data.

Data Extraction: The iPaaS securely extracts the relevant data payload from the source system's API endpoints.

Data Transformation & Mapping: The extracted data is transformed and mapped to the target system's canonical data model. This involves field-level mapping, data type conversions, and applying complex business rules using the iPaaS's visual designer and AI-assisted tools.

Data Validation: AI-powered validation checks ensure data quality, consistency, and adherence to business rules before posting to the target system. Anomalies are flagged for review or auto-correction.

Data Loading: The transformed and validated data is securely loaded into the target ERP system via its respective API endpoints.

Error Handling & Monitoring: Throughout the process, the iPaaS logs all transactions, handles errors with automated retries and dead-letter queues, and provides centralized monitoring dashboards with real-time alerts.

Data Touchpoints

Master Data: Customer (E9) <-> Business Partner (S/4HANA), Part/Product (E9) <-> Material (S/4HANA), Vendor (E9) <-> Business Partner (S/4HANA)
Sales & Fulfillment: Sales Order (E9) <-> Sales Order (S/4HANA), Shipment (E9) <-> Outbound Delivery (S/4HANA), Inventory (E9) <-> Inventory (S/4HANA)
Procurement: Purchase Order (E9) <-> Purchase Order (S/4HANA), Receipt (E9) <-> Goods Receipt (S/4HANA)
Finance: Invoice (AR/AP E9) <-> Billing Document/Supplier Invoice (S/4HANA), Payment (E9) <-> Payment (S/4HANA), General Ledger Entry (E9) <-> General Ledger Entry (S/4HANA)

"The integration architecture features a central iPaaS layer connecting Epicor E9 and SAP S/4HANA. Business events from either system trigger real-time data extraction.

Our iPaaS provides a visual mapping canvas, AI-assisted suggestions, and advanced transformation capabilities to ensure data integrity and consistency for critical business entities.

Customer / Business Partner

Synchronizing customer master data is fundamental. Epicor E9 uses 'Customer' for buying entities, while SAP S/4HANA centralizes all relationships under 'Business Partner' with various roles (e.g., FLCU00 for Customer, FLVN00 for Vendor).

Epicor E9 Fields

CustNum (PK) Name Address1 City State Zip Country PhoneNum EmailAddress TermsCode CreditLimit SalesRepCode

SAP S/4HANA Fields

BusinessPartner (PK) BusinessPartnerCategory FirstName LastName OrganizationName EmailAddress PhoneNumber StreetName CityName PostalCode Country TaxNumber Customer (Role ID) Supplier (Role ID)

Mapping Notes

Requires careful mapping of Epicor E9's single customer record to SAP S/4HANA's Business Partner structure, including assigning appropriate Business Partner Roles (e.g., FLCU00 for customer role). Unique identifiers (e.g., external Customer ID) are crucial for bi-directional sync. Address validation and standardization are often needed.
