Ariba QRCode Application

Introduction

This is an SAP HANA Cloud Platform Web application that shows how to search for catalog items and submit requisitions using the Ariba P2P API.

There are two possible usage scenarios for this application:

• [Scenario 1]: Scan a QR Code to show details about a specified item and submit a requisition through the application UI.
• [Scenario 2]: Scan a QR Code to submit requisition without starting the application UI.

Prerequisites

1. Eclipse installed with SAP HANA Cloud Platform Tools plugins.
2. JDK 1.7 set as an Installed JRE in Windows > Preferences > Java > Installed JREs.
3. Java Web Tomcat 7 set as a runtime environment in Windows > Preferences > Server > Runtime Environments.
4. Destinations configured for connecting to the Ariba API.

Build and Deploy the Application

1. Clone the Git repository.

2. Import the project as a Maven project into your Eclipse workspace.

Note: Make sure you use JDK 1.7 for this project. You can configure this in the project build path.

3. Run the requisition-parent project with Maven goal clean install.

4. If you are deploying the application locally, see Creating and Deleting Destinations Locally.
   If you are deploying it on the Cloud, see Creating and Deleting Destinations on the Cloud.

5. Deploy the application.

Note: Make sure you select the Java Web Tomcat 7 as a runtime environment.

6. To access the application, follow the steps described in the Access the application section.

Configure the Destinations

You need to configure an HTTP Connectivity Destination for this application before running the project.

Note: To learn more about how to configure the destination, see [SAP HANA Cloud Platform Destinations Documentation] (https://help.hana.ondemand.com/help/frameset.htm?e4f1d97cbb571014a247d10f9f9a685d.html).

The HTTP API Destination looks like this:

Name=ariba-p2p-api
Description=Ariba P2P SOAP WS API Destination
Type=HTTP
URL=https\://<Ariba instance>/Buyer/soap/<Ariba realm>
User=<endpoint-user>
Password=<endpoint-password>
Authentication=BasicAuthentication
ProxyType=Internet
deliverTo=<deliver to name>
headerUniqueName=<header>
shipTo=<shipping address>
billingAddress=<billing address>
originatingSystem=<originating system>
passwordAdapter=PasswordAdapter1
preparer=<preparer user>
requester=<requester user>
originatingSystemId=<system id>
businessUnit=<business unit>
CommonCommodityCodeDomain=<common commodity code domain>
CommonCommodityCodeName=<common commodity code name>
requisitionComment=<comment for requisition>
requisitionName=<requisition name>
namespaceXMLNSvariant=<namespace XMLNS variant>
partNumberItem1=<supplier part number 1>
partNumberItem2=<supplier part number 2>
partNumberItem3=<supplier part number 3>

Access the application

In both scenarios you need to generate a static QR Code of type URL. You can use your preferred QR Code generator. If you deploy the application on the cloud, this is the URL pattern that you use to access it: http://<application><account>.<domain>/qrcode-app/

If you run the application locally, then use this URL pattern: http://<host>:<port>/qrcode-app/.

Scenario 1

1. Generate the QR Code using this URL pattern: http://<application><account>.<domain>/qrcode-app/#/item/<item_part_number_in_Ariba>, or http://<host>:<port>/qrcode-app/#/item/<item_part_number_in_Ariba>.
2. Use a QR code scanner from your mobile device to show the details about this item in the application UI and submit the requisition.

Scenario 2

1. Generate the QR Code using this URL pattern: http://<application><account>.<domain>/qrcode-app/api/v1/requisition/submit?partNumber=<item_part_number_in_Ariba>&quantity=<quantity_of_the_item_to_be_ordered> or http://<host>:<port>/qrcode-app/api/v1/requisition/submit?partNumber=<item_part_number_in_Ariba>&quantity=<quantity_of_the_item_to_be_ordered>.
2. Use a QR code scanner from your mobile device to submit the requisition with the specified item and quantity.
