Introduction


Hey there, fellow techies! As businesses continue to rely on technology for growth and success, it's time to shake things up with some ChatGPT magic!

We've all heard the same old stories - developers using ChatGPT to generate code, script writers churning out viral content, copywriters producing content at lightning speed. But what if we told you there's a new way to use ChatGPT that'll blow your mind?

As someone from a SAP background, I knew I had to do something totally epic with this technology. And guess what? I did! But don't worry, it's not another ABAP code - we're way too cool for that!

By integrating ChatGPT with SAP S/4HANA, we can revolutionize the way businesses operate. We're talking natural and efficient communication that saves time and increases productivity. It's like having a secret weapon that'll take your business to the next level!

So, buckle up and get ready to discover how ChatGPT integration with SAP S/4HANA can change the game. It's time to think outside the box and embrace the endless possibilities of this amazing technology!

Business usecase


Picture this: You're a supplier and your inbox is overflowing with emails about purchase orders. Your customer support expert is slogging through the SAP system like a snail on a rainy day. It's slow, it's tedious, and you're ready to pull your hair out!

Well, hold onto your hats, folks, because ChatGPT integration with SAP is here to save the day! Say goodbye to tedious manual tasks and hello to relatively automated fast responses. It's like giving your business a shot of espresso straight to the veins!

 

You might be thinking, "what big deal, Isn't he just a chatbot crap trying to sell?" But creating a chatbot for SAP requires a relatively more development, including training the bot with intent, developing different skills, and testing it extensively. It can be a time-consuming and expensive process.

 

That's where ChatGPT integration with SAP stands out. With good prompt engineering, you can use ChatGPT to generate  context in JSON format from customer queries which could be used as input for API and seamlessly integrate with the SAP system to retrieve infortmation in JSON/XML format and generate meaningful text from that JSON/XML. In just two hours, you can have a fully functioning customer support system that can respond to queries with meaningful replies over email.

It's generative AI at its best. Instead of relying on traditional chatbot type development, you can harness the power of ChatGPT and SAP integration to make your business more efficient and productive. The possibilities are endless, and it's just one example of how technology can transform the way we do business.

 

Technical Architecture



 

 

Listen up, folks! If you want to integrate ChatGPT with SAP S/4HANA, you're gonna need some important tools in your arsenal:


First up, we've got Azure Logic App - the cloud-based hero that'll help you develop the integration between ChatGPT and SAP S/4HANA. This thing is like the Robin to your Batman!

But wait, there's more! You'll also need an OpenAI ChatGPT API key - it's the key that unlocks the magical ChatGPT model that makes everything possible.

And let's not forget about the SAP S/4HANA system itself. This is the big boss that holds all the important info, so make sure the Standard Sales Order API is properly configured in the S/4HANA system.

Now, things start to get a bit technical, so bear with me. You'll need to install the SAP Cloud Connector in the same network as the SAP S/4HANA system. It's like a secret agent that'll establish a super secure connection between the SAP S/4HANA system and Azure Logic App via SAP API Management.

Last but not least, we've got the SAP API Management. It's like the bouncer at the door, making sure only the cool cats get in. It's part of the SAP BTP Integration Suite and will help you develop a wrapper API on top of Standard Sales order API that can be accessed from Azure Logic App.

So, there you have it, folks! With these tools in your utility belt, you'll be ready to take on the world of ChatGPT and SAP integration like a boss!

 

Alrighty, folks! It's time to connect the dots and get this party started!


Step 1: Activate SAP Sales Order API in S/4HANA , get some inspiration from this official sap help document.

Step 2: Test the odata service in Postman


Step 3: Install and configure SAP Cloud Connector, there are many blogs which covered this topic but i am dropping here the link of official sap help documentation.

Step 4: Consume S/4HANA OData API in SAP API Management follow this blog.

Step 5: Test ChatGPT to generate JSON from from customer query

I have observed in Azure Logic App email body get stored as html text rather than normal one, but not to worry ChatGPT is quite powerful to extract the context and put into JSON form without any problem


Step 6: Test ChatGPT to generate meaningful email from SAP API Response



Step 7: Get a API Key and Try out the ChatGPT Latest Model turbo via Postman

Login to OpenAI Platform,Navigate to API Key section in Account and Create API Key Secret


 


More details about ChatGPT API Usage could be found in their documentation page

Alright, folks, it's time to wrap this bad boy up with a bow on top! We've covered everything from snails on rainy days to fire-breathing dragons, and I think we can all agree that ChatGPT and SAP integration is the shot of espresso our businesses need. So don't be a snail, embrace the power of ChatGPT and SAP, and let's revolutionize the way we do business! And hey, before you go, don't forget to share this blog with your friends and colleagues. If they don't like it, tell them it was a viral marketing experiment gone wrong.

** I understand how valuable it is to have practical demonstrations when learning new concepts, and this blog is designed with that in mind. We're utilising the public version of ChatGPT in this instance, purely because the Azure Open AI service wasn't accessible for individual developers at the time of writing this blog. I appreciate your understanding on this.


However, I'd like to emphasise that for real-world, enterprise-level applications, it is essential to employ a dedicated Azure Open AI service instance. This is vital not only to address and uphold the principles of the General Data Protection Regulation (GDPR) but also to ensure other security measures are effectively in place. It's all about safeguarding your data and ensuring the integrity of your applications, and we take this very seriously. Thank you for your understanding and support.


Also very important to know this blog doesn't cover email authentication and authorization. In Part 2, I'll show you how to handle it, and it should be included in the general template. Heaven forbid I should suggest that anyone ship this blog to production without making the necessary adjustments themselves!
