Handling RFC in SAP Build - Process Automation

[Metehan]

Introduction

Hello,

I will be showing you How to handle RFC in SAP Build - Process Automation .

Scenario

We will be using a RFC to get data that we need in our automation.

Prerequisites:

1. Basic Knowledge about RFC


2. Basic knowledge about SAP Build


3. Basic knowledge about SAP Process Automation.

Step-by-Step Procedure:

1. Creating the RFC .


2. Creating the Process Automation project.


3. Consuming RFC in our project

STEP 1 : Creating RFC

Firstly we need to create our RFC according to our needs. Go to ' SE37 '  transaction and create your RFC. Do not forget to select Remote-Enabled Module processing type.

In my case, what I needed was the mail addresses of customer numbers I already had. So created my RFC to get mail addresses using company codes and customer numbers. You should set your parameters according to your needs.
You can see my parameters below.

Image 4 - T_CUSTOMER Components

In my coding part I am finding mail addresses using the customer numbers and company code provided in T_CUSTOMER and filling ' MAIL '  component according to ' IV_ CHECK ' import parameter.

STEP 2 : Creating Process Automation Project

Now we are going to create our project.

Go to SAP Build cockpit and click create.

After that click ' Build an Automated Process ' and ' Task Automation ' . Give your project a name and configure your agent and we are all set.

STEP 3 : Consuming RFC in Project

Firstly we need to add BAPI SDK to our project. To do that go to settings and then Dependencies section. After that click Add Dependency and search for BAPI SDK.

Now we need to create our Data Types based on our RFC parameters. The important part here is that Data Types must be created as structures, for my case I will be creating two Data Types , one for Import Parameters of my RFC and one for Tables Parameters.

Go to your Project Content and click Create then click Data Type. After that give it a proper name and lets set the Data Type.

Create your Data Types based on your RFC parameters. Here are my Data Types

Now we can call our RFC from our project. Lets start building our project. You can see the general overview of project, I will be explaining each step.

Firstly we need to establish our connection to SAP server where RFC exist. For that we are using Set SAP Connection (Basic) activity and filling it as needed.

To be sure whether we were able to connect to SAP system or not we are using Is SAP Connection Alive activity.

For next step we are creating our variable using the Data Types that we created.

Now that we created our variables , we are going to fill these variables. Firstly we are checking if the SAP Connection is alive or not after that we are filling our variables as we need.

Now we can execute our RFC and get the desired data. To call our RFC we are using Execute BAPI activity. And to reach our desired data we are using output parameter of Execute BAPI in a Custom Script activity as you can see below.

Here is our mail addresses corresponding to customer numbers and company codes.
