High- Level Specification

Functional Overview

Ariba Guided Sourcing is interfaced with SAP ECC system (PRS) to sync Supplier Master Data. Bidders and Supplier Contacts Master Data is maintained in Ariba Guided Sourcing directly. The Supplier Master Data (including Bidders) along with Supplier Contact information is interfaced with Keelvar as well to allow the Sourcing Specialists the flexibility to invite participants to Keelvar Event. Ariba Supplier ID (System ID) is maintained as External ID in Keelvar ensuring the sync between the two systems. Whenever a supplier or Bidder is deactivated in Ariba Guided Sourcing, the supplier is also archived in Keelvar.

Scope and Objectives

The scope of this Functional Specification is to describe the interface between Ariba and Keelvar for synchronizing Supplier Master Data. Whenever a supplier/bidder is created in Ariba Guided Sourcing, the supplier will be pushed to Keelvar using Keelvar Supplier Management API. Similarly, whenever, a supplier/bidder is deactivated in Ariba, the Keelvar supplier record will be archived. Ariba Master Data API for Sourcing will be used to extract the data from Ariba Guided Sourcing

Process Flow Diagram

Assumptions

• Following three fields have been added to the Supplier object in Keelvar:

Dependencies

• Depending on the build of ERP-116 Integration of Suppliers from SAP PRS (ECC) into Ariba

Security, Integrity and Controls

The following are the Security and Authorization considerations for this interface:

• Access to Ariba and Keelvar APIs is limited via a shared secret to secure End Point connection
• Access to API authorization in SAP Ariba Sourcing are being addressed by Ariba standard security controls. Only authorized persons with Ariba administrator’s role can access/ change API OAuth Keys.
• Similarly, access to API authorization in Keelvar are being addressed by Keelvar standard security controls. Only authorized persons with Keelvar Organization User role can access/ change the Keelvar authorization token.

Configuration Requirements

In order to activate the Master Data API for Soru, following steps need to be completed:

1. Sign in to the SAP Ariba Developer Portal.
2. Click Create application from the home page.
3. Fill out the Create a new application form by entering an application name and description, then click Submit.
4. This generates an Application key that identifies your application within the system. Every API request your application makes must include this key as the value of the apiKey parameter.
5. Ask your organization admin to request API access for your application by displaying the application in My applications and clicking Actions  Ask your admin to request API access.
6. A user with the Organization Admin role requests approval for API access.
7. SAP Ariba assesses the request, and once processed and approved, the Organization Admin user receives email with an OAuth client ID for the application.
8. A user with the Organization Admin role generates the OAuth secret and base64-encoded client and secret.

In order to activate Keelvar API, following steps need to be completed:

1. Log into Keelvar Portal
2. Go to Account settings and navigate to API Keys section
3. Click New token button and provide the name and Expiration of the token. Click create to get the token details.

Ariba Guided Sourcing configuration details are described as under:

Keelvar configuration is described below:

Processing Logic

Processing within Source

Processing within Middleware

A Scheduled Task in SCPI should run and extract all supplier updated in Ariba since the last run as under:

curl --location 'https://eu.openapi.ariba.com/api/sourcing-mds-search/v1/prod/entities/organizations?%24filter=((TimeUpdated%20gt%20dateTime))&%24includeInactive=true' \
--header 'Accept-Language: en' \
--header 'X-Realm: ARIBA_REALM_ID' \
--header 'Accept: application/json' \
--header 'Authorization: Bearer ARIBA_TOKEN' \
--header 'apiKey:  ARIBA_API_KEY'

For each of the supplier, the logic is as under:

• If 'Active= true' extract the Supplier Contact Details from Ariba as under:

curl --location 'https://eu.openapi.ariba.com/api/sourcing-mds-search/v1/prod/entities/users?%24filter=(PasswordAdapter%20eq%20%27SourcingSupplierUser%27%20and%20Organization.SystemID%20eq%20%27<SystemID>%27)& \
--header 'Accept-Language: en' \
--header 'X-Realm: ARIBA_REALM_ID' \
--header 'Accept: application/json' \
--header 'Authorization: Bearer 2ARIBA_TOKEN' \
--header 'apiKey: ARIBA_API_KEY'

The first user object available in the response payload along with the first organization payload should be used to create a request payload to Keelvar as under:

Sample JSON for the payload is available here -

Then, a request to Manage Supplier Change request should be made as under:

curl --location 'https://test.keelvar.dev/api/manage/supplier_changes' \
--header 'Authorization: Bearer YOUR_API_KEY' \
--header 'Content-Type: application/json' \
--data-raw 'PAYLOAD_CREATED_AS_ABOVE_JSON';

• If 'Active= true' a payload should be created with the Organization ID as under:

Sample JSON for the payload is available here -

Then, a request to Manage Supplier Change request should be made as under:

curl --location 'https://test.keelvar.dev/api/manage/supplier_changes' \
--header 'Authorization: Bearer YOUR_API_KEY' \
--header 'Content-Type: application/json' \
--data-raw 'PAYLOAD_CREATED_AS_ABOVE_JSON';

Add logic for Supplier User update.

Interface Dependency

•  This interface should always be run after the ERP-116 Integration of Suppliers from SAP PRS (ECC) into Ariba interface has been completed

Interface Constraints

Rate Limit for Ariba Event Management API - (Requests): 5/second, 80/minute, 3500/hour

Rate Limit for Keelvar create/update Event API - Burst (120/hour), sustained (500/day)

Delta or Full Load Requirements

All requests for creation and update of sourcing events are done via delta load since last run.

Interface Alert & Monitoring

The following should be monitored:

• API endpoints are available.
• Keelvar token expiration.
• Failures on inbound processing and outbound side need to be handled . Please check the Error Handling section.
