Functional Overview
CIG add-on provides standard integration program to integrate some master data from SAP ERP system into Ariba.
However, for the Currency Conversion Rates, the source will be the ECC but without the CIG add-on installed thus the decision is to have this go through Syniti as well.
The middleware to be used to implement the end-to-end integration will be SCPI. This document will explain integration point of Syniti to SCPI.
Scope and Objectives
Below is the required Master Data for Ariba Guided Sourcing that need to be interfaced.
- CurrencyConversionRate.csv
Process Flow Diagram
Step | Description | Comment |
|---|---|---|
1 | The execution of the interface is triggered as per the defined job schedule | |
2 | Syniti will generate the CurrencyConversionRate.csv files with correct filename based on the structure required by Ariba Sourcing and zipped this | |
3 | Syniti will call a service in SCPI to send the zipped CSV file to SCPI | |
4 | SCPI will then push the zipped CSV file embedded on the SOAP message based on the required structure/parameters to the CIG endpoint | |
5 | CIG will push the payload request to the Ariba Parent endpoint | |
6 | The data in the CSV file get uploaded into Ariba Parent and replicated to Ariba Sourcing realm |
Assumptions
- Syniti is able to extract the required master data which are standard SAP data
- Syniti can zip the CSV files and send these to SCPI by calling a service
- SCPI uses CIG standard SOAP format both for connectivity and pushing the data to CIG
Dependencies
System interface from Syniti to generate the Currency Converstion Rate csv file, zip it and call a service in SCPI.
Security, Integrity and Controls
The following are the Security and Authorization considerations for this interface:
- Define a Web Services Security certificate and/or the shared secret key to use to secure the End Point connection.
- Access to interface parameters in SAP Ariba Sourcing are being addressed by Ariba standard security controls. Only authorized person with Ariba administrator’s role can access/ change interface parameters.
- Web service security configuration allows secure communications protocol provides a means for applying security to Web services.
Configuration Requirements
- Enable the parameter Application.AQS.EnableCurrencyConversionRateSetSync when interfacing Currency Conversion rate into Ariba Procurement solution and make it available for use in Ariba Sourcing solution, for suite-integrated sites.
Special Requirements
Not applicable
Design Rationale
Since there is no S/4HANA system for R2, it is needed to use another system as source. ECC can be used but this solution will use Syniti as the source because Syniti has the cleansed data available.

Processing Logic
Processing within Source
- Syniti prepares a zipped CSV files based on the target structure requirements and calls a service in SCPI to send the zip files to SCPI.
- The CSV filename should be followed as shown below. The zip filename can be anything but the recommendation is to have a date stamp (CurrencyConversionRate_07222025.zip)
- CurrencyConversionRate.csv
Processing within Middleware
- SCPI will receive the zipped CSV files from Syniti
- SCPI will embed the zipped CSV files in base64 to CIG via the CIG endpoint URL (as stated below) following the standard SOAP message structure
- CIG endpoint URL for Master Data (EU Data Center):
Test instance: https://testacig.ariba.com/cxf/receiveERPMD
Production instance: https://acig.ariba.com/cxf/receiveERPMD
- CIG endpoint URL for Master Data (EU Data Center):
- For the Sourcing MD, below is the example payload request. Note that the value for the realm parameter will change based on the Ariba realm where the master data will be interfaced to.
- For the Currency Conversion Rates, the soap message will be the same for the Sourcing MD except for some differences as stated below:
- The Ariba event name to be called is Import Batch Data
- Value for the Solution parameter will be Buyer
- There is only 1 system ID parameter
- There is no operation parameter as this will already be covered by the fullload parameter
Processing within Target
Ariba Master Data Import tasks enables exchange of data between SAP ERP and SAP Ariba Sourcing using SAP Integration Suite, Managed Gateway for Spend Management and SAP Business Network.
Interface Dependency
Interface Constraints
The maximum file size for a CSV or ZIP that is imported via the Ariba Administration area is 40MB, this applies to all Ariba solutions.
The same "Import Master Batch Data" event is triggered for the other master data below, which should be considered during batch job scheduling if they will be interfaced and will be zipped separately.
Delivery Requirements
Delta or Full Load Requirements
The CSV file will contain the delta. The way Ariba loads these rates are technically in delta mode.
Interface Alert & Monitoring
The following should be monitored:
- Interface is active (both inbound, process and outbound component)
- Failures on inbound, processing and outbound side need to be handled (restart, if still failure; skip and communicate)
- Messages are processed in reasonable time (XX elapse time)
Interface Reporting
There are no specific reporting requirements for this interface.

Performance Consideration
Error Handling
The interfaces are based on standard integration content, mainly standard data mapping, so errors are unlikely but there are still foreseeable error scenarios related to data selection, data content, or data mapping.
Administrators can check errors using the following methods:
- Configure email notification alerts on the SAP Ariba application system to receive notification when an error occurs. This enables the administrator to log in to the SAP Ariba application to check the details of the errors.
- Directly log in to the SAP Ariba application, go to Administration or Core Administration > Integration Manager > CIG (Managed Gateway for Spend&Network) >
Visit the SAP Integration Suite, managed gateway for spend management and SAP Business Network (Europe Data Center) and check the details of the error. - Directly log in to the SAP Ariba application, go to Administration or Core Administration > Integration Manager or Site Manager > Import (Import Master Data Batch Pull) and check the details of the errors.
- To correct the error, the administrator must ensure that the data inconsistency is resolved in the Syniti system and then must rerun the tasks for the Master Data again from the source system.
Testing
How to Test
Test Conditions and Expected Results
| ID | Condition | Expected Results |
|---|---|---|
| Currency Conversion Rates are valid and complete | Data will be loaded to Ariba Parent realm and replicated to Ariba Sourcing | |
| Rates for specific currency is updated | Updated rate is loaded to Ariba Parent and replicated to Ariba Sourcing |
Test Considerations/Dependencies
Test data need to be available in ECC for Syniti’s extraction.
