High-Level Specification

Functional Overview

The objective of this integration is to establish a robust middleware process that facilitates the automated transmission of Currency Exchange Rate Master data from SAP ECC(PRS, PF2-050) to the Icertis Contract Intelligence(ICI) platform. The integration ensures that Icertis always has up-to date currency and exchange-rate information essential for contract calculations and validations. This process performs the following functions.

• Receives currency and exchange-rate data from SAP ECC (PRS, PF2-050) through the ERP-110 Interface.
• Maps and transforms the data to align with the structural and validation requirements of the Icertis APIs.
• Orchestrates the end-to-end data flow, including transmission, response handling and error management.

This integration is triggered daily through a scheduled job to ensure that Icertis consistently receives the most recent exchange-rate information required for contract evaluation and processing.

Scope and Objectives

• Scope:
  This request covers the end-to-end integration required to transform and create/update currency exchange rate data flowing from SAP ECC (PRS, PF2-050) to Icertis. It includes the middleware logic, data mapping, orchestration, and exception handling necessary to ensure accurate and reliable data transmission.
• Objectives:
  • Automate the transfer of currency and exchange rate data from SAP ECC(PRS, PF2-050) to Icertis.
  • Ensure that the data is transformed and mapped according to Icertis API specifications.
  • Handle exceptions, retries and monitoring to ensure the process runs reliably.
  • Create a custom integration that connects SAP ECC (PRS, PF2-050) and Icertis so that currency exchange rates can be synchronized smoothly.

Process Flow Diagram

Assumptions

• SAP ECC (PRS, PF2-050) serves as the authoritative source for clean and validated currency and exchange rate data.
• Icertis APIs for currency master data ingestion are fully configured, available, documented, and accessible for integration.
• The middleware platform SAP CPI, reliably supports secure API communication, comprehensive error handling, and transaction-level logging.
• Performance benchmarks are satisfied, ensuring that data transfers complete successfully within the defined batch processing window.

Dependencies

• ERP-110 (Source system interface) and ERP-290 (Target system interface) must be available and operational to facilitate seamless data exchange. 
• Currency and exchange-rate data in SAP ECC(PRS, PF2-050) must be updated in timely manner to ensure accuracy and consistency.
• Scheduled batch job execution in SAP ECC (PRS, PF2-050) must be maintained to support timely data extraction and transmission

Security, Integrity and Controls

Secure authentication mechanisms are in place at middleware for access to both SAP ECC and Icertis systems:

• Secure HTTPS protocol is used for all data transfers between the middleware and SAP ECC, ensuring encrypted communication and protection against unauthorized access.
• OAuth 2.0 authentication is implemented for accessing Icertis APIs via an Azure-registered application, providing token-based security and controlled access
• Audit logging captures all integration transactions, including timestamps, request/response metadata, and error details for traceability and compliance.

Configuration Requirements

• Azure Application Registration

  • Since Icertis relies on Azure Active Directory as its identity provider (IdP), an application must be registered in Azure to enable OAuth 2.0 token generation and validation. This establishes trusted access between the middleware and the Icertis APIs.

  • The application registration includes defining the client ID, client secret, scope, and API permissions required to access the Icertis endpoints.

Design Rationale

This interface is designed to facilitate seamless integration between Syniti (source) and Icertis (target) for currency/exchange rate master data. The middleware orchestrates the data flow, ensuring mapping, transformation, and reliable delivery

Data Structure

The following fields will be used to provide the required data structure of the interface:

Requested Sample (Extract from SAP ECC):

 Currency conversion file generated as per ERP-110 Currency Conversion into Ariba .FS should be re-used for Icertis as well. CPI will filter out the EUR conversion rate.

 Transformation in CPI (Icertis required format):

Processing Logic

• Inbound Trigger

  • CPI receives the currency exchange rate data file from SAP ECC(PRS, PF2-050).

• Data Validation

  • If any record fails validation, CPI rejects the entire batch and sends an error notification to the Integration support.

• Transformation

  • CPI applies any required transformation rules:
    • Maps source field names/formats to the target structure required by Icertis

• Routing

  • CPI routes the validated data to the next integration step (e.g., prepares payload for Icertis Business API).
  • Ensures secure transmission (e.g., via HTTPS, OAuth2).

• Error Handling

  • If any error occurs during processing (validation, transformation, routing), CPI logs the error, stops the process, and sends an alert to the Integration support team.
  • No partial loads—either the entire batch is processed successfully, or it is rejected.

• Monitoring & Logging

  • CPI maintains detailed logs for each integration run.
  • Job status, error details, and audit trails are available on the CPI monitoring dashboard.
  • Email alerts are sent for failures.

Delta or Full Load Requirements

• Full Load:
  • The interface always pushes the complete set of exchange rates for all supported currencies.
  • No delta tracking is required since the data is refreshed daily.

Language Requirements

• No multilingual support required for exchange rate data.
• All fields are numeric or standard ISO codes.

User Interface Requirements

Not Applicable

Volumetrics

• Daily load of 70 currency pairs to be created/updated in bulk
• The first load will create the currency exchange masterdata
• Subsequent loads will update the existing currency exchange masterdata

Performance Consideration

Scheduling and Execution Window

• The integration job should be scheduled during off-peak hours (e.g., early morning) to avoid contention with other system processes.

Error Handling

1. Validation Errors

• Cause: Missing mandatory fields, invalid currency codes, negative exchange rates.
• Handling:
  • Reject the whole batch.
  • Log the error with detailed message.
  • Notify integration support team via email or dashboard.
  • Continue processing remaining records.

2. API Failures

• Cause: Icertis Business API is unavailable, authentication failure, timeout.
• Handling:
  • If retries fail, log the failure and raise an alert.
  • Notify support team with error code and timestamp.

3. Data Load Failures

• Cause: Payload formatting issues, bulk upsert failure.
• Handling:
  • Validate payload structure before submission.
  • Use staging logs to identify failed records.
  • Allow manual reprocessing of failed records.

4. Partial Success

• Cause: Some records succeed, others fail due to validation or API issues.
• Handling:
  • Reject the whole record and notify the admin team on failure

5. Monitoring and Alerts

• Tools: Integration monitoring dashboard, email notifications, log files.
• Recipients: Integration support team, business operations team.
• Alert Types:
  • Job failure

 Interface Alert & Monitoring

• Alerts should be configured for:
  • API failures
  • Validation errors
• Monitoring tools (middleware logs) should notify:
  • Integration support team
  • Business users (email)
• Retry logic should be in place for transient failures.
