Introduction:

In this article, I have highlighted some simple steps to integrate Power Platform’s Power Virtual Agents with SAP Gateway Demo System – ES5 to create a Chatbot for Microsoft Teams which fetches product information from the SAP system based on user inputs.

Thanks to some fantastic YouTube videos from Holger Bruchelt and the help provided.

It was really easy to get started and get my hands dirty with Power Virtual Agents bots

The intent of this blog is to emphasize how easy it is to create, deploy and integrate Power Platform with SAP System.

The Power Platform is an intuitive, extensible platform of low-code tools that empower users to build apps, automate processes, and analyze data, including SAP data. Solutions built on the Power Platform enables organizations to get more out of their SAP data, from deeper analysis and reporting to more efficient, SAP-driven business processes.

Power Virtual Agents lets you create powerful chatbots that can answer questions posed by your customers, other employees, or visitors to your website or service. Power Virtual Agents is available as both a standalone web app, and as a discrete app within Microsoft Teams.

1. Develop Chatbot using Power Virtual Agents

2. Creating Topics for the Chatbot

The starting point of a chatbot is Topics. In Power Virtual Agents, a topic defines how a bot conversation plays out. You can author topics by customizing available templates, create new topics from scratch, or get suggestions from existing help sites.

You may enter other details as follows:

A topic has trigger phrases, these are phrases, keywords, or questions that a user is likely to type.

A trigger phrase is a phrase that a customer enters in the chat window to start a conversation with the bot. Once the conversation is started, the conversation follows the path you define.

This specific Topic would be triggered based on user inputs provided to the bot during an interaction.

The AI uses natural language understanding to parse what a customer actually types and find the most appropriate trigger phrase or node. For example:

3. Creating conversation path for topic:

You would need to create a conversation path for this bot to interact with the end-user. This can be created by selecting Go to authoring canvas:

Below is an example of the user interacting with this bot:

• The user inputs are matched with Trigger Phrases to find the most relevant trigger phrase.

• As per design flow, a message is displayed to the user to look up products.

• In this step, a question is asked to the user and the response is captured in a variable.

• The next step has a call to action based on the user input captured in the variable. The action here is to Create a Power Automate Flow

In this flow, the user input variable is passed as a Product ID through Get product functionality, that connects to the SAP system through a custom OData connector. As a result fetches the corresponding Name,  Description, and Price of Product ID.

• The values returned from SAP system can be further displayed to the user through the Message.

This flow of Power Automate is ready now and can be tested through the Test bot option:

Final thoughts & Call to action

This is a basic example of a Chatbot created using Microsoft Power Platform and integrated with SAP Gateway Demo System – ES5. I have used Get product functionality to get the data from the above SAP system. There are many more functionalities that can be implemented with a similar integration approach. I hope you find it simple to integrate and set up. I would strongly encourage going through the references below for a detailed understanding of the topic.
