In this blog, I will take you through the steps for creating a bot via SAP Intelligent RPA 2.0, through which you can post data into SAP S/4HANA Cloud via REST APIs.

SAP Intelligent RPA 2.0 uses a new Low-code/No-code approach for bot creation and this significantly reduces the load on developers.

Introduction

With the desktop studio application, developers are free to create custom SAP Intelligent RPA bots which simplifies days to day tasks by reducing human intervention.

Enter the bot name and click on create.

This will create a new project and will open the project in a new window.

Under the contents, tab, Click on Create and then select Automation

Provide the necessary details and click on create

This will create a new automation with an empty workflow as shown

Let us create two input variables for providing username and password of type String. This can be done by going to the I/O tab and adding two input parameters as shown

The next step will be to encode the username and password. The encoded string can be used to make the REST API calls.

Search for Encode String under the tools tab to get the Encode String activity.

Drag and drop this activity to the RPA workflow as shown below

You will now see that the activity has a red highlight. This is because it expects an input to be encoded.

Click on the activity Encode String. This will open the input fields for the activity. Select the highlighted button next to the input
