This blog post brings to you a new content Ariba Purchase Requisition Approvals which enables the procurement experts to automate the approval of Purchase Requisitions created in SAP Ariba, using the capabilities of SAP Workflow Management, in a flexible and transparent way. Workflow Management is the process of digitizing discrete processes and managing the outcomes. And workflow management software allows you to build, run, and manage workflows.

SAP Ariba has its own approval process. This content package is developed based on the feedback received from some of the SAP Business Technology Platform customers who are looking for managing the approvals centrally via common BTP Workflow Management framework. Hence that brings the need to configure such external approvals of the purchase requisitions created in SAP Ariba via BTP Workflow. The process can be configured for internal approval (within SAP Ariba) or external approvals via the SAP Workflow Management.

A purchase requisition is a request that is made to the purchasing organization to procure a certain list of items and needs approval from the purchasing organization. When a Purchase Requisition marked for External Approval is received from SAP Ariba, a pre-configured process variant is triggered in SAP Workflow Management via the integration flow configurations. The approvers are determined based on the incoming purchase requisition’s data. The purchase requisition is either Approved or Rejected based on the approvals performed in the process and the document is updated back in SAP Ariba.

The workflow content package is published on SAP API Business Hub with the following artifacts, and it works in conjunction with the Integration package ‘SAP Ariba Integration with SAP Workflow Management - Purchase Requisition Approvals.

Solution Architecture

The below solution diagram explains the involved technical artifacts and how Purchase Requisitions data are extracted from SAP Ariba using the Cloud Integration capability of SAP Integration Suite. An approval workflow is created, and the approval tasks are assigned to the determined approvers using the Business Rules capability of SAP Workflow Management.

Manage Decisions

The business process expert can modify the decisions and polices based on the business needs using the Manage Decisions application. The package provides flexibility in determining the Cost Center, Quality Check and Global Purchasing approvers through the Business Rules capability of SAP Workflow Management and any other business group of approvers can be determined from other external applications.

Approver Determination Strategy

A purchase requisition consists of header and line items data. This content package focusses on the approval of incoming requisition documents at header level, from essentially three approval groups namely Cost Center, Quality Check and Global Purchasing Organization.

The content is developed such that it makes sure all the line items within the incoming requisition documents are looped through to determine the cost center approvers using the Loop Function FOREACH within a Text Rule for Execute Operations available in the Business Rules capability.

Determine Cost Center Approvers

Once the cost center approval is through, the next steps of Quality Check and GPO approval will be triggered based on the configured process variant, which will create subsequent approval tasks for designated approvers based on the business rules configuration.

Live Process Insights

The business process expert can gain end-to-end visibility on process using the out-of-box Visibility dashboard based on the pre-configured visibility scenario. The Process Workspace provides real-time insights into critical business-related situations of the running process and thus helps identifying bottlenecks well on time.

Process Flow

When a Purchase Requisition configured for external approval is created in SAP Ariba, the approval flow gets triggered based on the configured process variant in the Workflow Management tenant on BTP. Approvers then receive tasks in their My Inbox application to approve or reject the document.

Setup integration between SAP Ariba and SAP Workflow Management

The Ariba Purchase Requisitions Approval Package works together with the Integration package SAP Ariba Integration with SAP Workflow Management - Purchase Requisition Approvals to automatically create an approval workflow or to start an approval process to approve and update the purchase requisition in SAP BTP.

Integration Package Overview

In your integration tenant, discover and import “SAP Ariba Integration with SAP Workflow Management - Purchase Requisition Approvals”. It consists of an Integration Flow which is called periodically by a timer. In addition, a Value Mapping to define regions based on company codes is provided. That region information can be used for approver determination. You can find more details in the setup and configuration guide which is delivered along with the Integration Package.

This concludes the blog post which essentially showcases how a purchase requisition created in SAP Ariba can be externally approved by designated approver groups using the capabilities of SAP Workflow Management and then posted back to the source system for further processing like Purchase Order creation etc.

The workflow content package Ariba Purchase Requisitions Approval is available for consumption along with its Integration Package on SAP API Business Hub. There are many more SAP Workflow Management content packages published across different industries and lines of business applications on SAP API Business Hub.
