How to Call ERP T-Code From C4C


In this Blog post we will describe how to call any T-code from C4C using HTML mashup, in most business cases we have an integration with ERP and always there is a need to access ERP T-codes from C4C without using GUI.

So here we will explain the process of calling T-code MMBE from C4C to check the material availability in ERP using HTML mashup


To launch any ERP screen from C4C, first we need to know the target system’s Port number and Host Name details to define the URL for the HTML mashup.

Login into ERP system (target system) and go to T-Code: SMICM.

Click on Go to- > Service

Capture the port and hostname information

Configuration Steps

Step 1: In the Administrator work center, go to Mashup Authoring:

Path: Administrator > Mashup Authoring


Step 2: Choose New > Html Mashup


Step 3: Choose a the name for the Mashup, in my case we are planning to launch the ERP T-code MMBE for checking the availability stock. We name it as “ Call S4hana MMBE ”


Step 4: The Port Binding decides on which screens the Mashup can be visible. In my example I want to launch the Mashup in the overview tab in sales order object. If you want to launch in any custom tab, then you need to define your own port binding. In my case, i select it “without post binding” to launch in overview tab.


Step 5:  In Configuration Information tab, set the Radio Button to HTML Code.

write the below code to call ERP screen

We have to add the T-code we are trying to launch and the URL for ERP screen as below.

<!DOCTYPE html>
   <title>Launch App</title>
<button onclick="myFunction()">Check Stock Availability</button>
<script type="text/javascript">
function myFunction() {
var par = "&~transaction=MMBE";
var url = "https://<Server>:<Port>/sap/bc/gui/sap/its/webgui?sap-Client=<Client>"+ par


URL explanation:

https://<Server>:<Port>/sap/bc/gui/sap/its/webgui?sap-Client=<Client> +Par;

We need to replace the server, Port and Client information in the sample URL with parameter information (T-Code you are launching & any input parameters to ERP screen etc…)

Step 5: Save the created Mashup and Activate it.

Step 6: to add the mashup in the required screen you can follow the below steps

In my case I want to show the mashup link in sales order, overview tab

So go to adaptation mode and add the mashup you created


Step 7:Then go back twice


 Step 8: until you reach to the view screen then click on View


Step 9:in my  case i want mashup to be appeared in Overview screen, so i will choose overview Screen


Step 10:Then choose add mashup


Step 11:Select mashup and click Apply


Step 12: here is the result you will find your mashup added in the overview screen as below


Step 13: End adaptation and click on mashup link

when you click on the link the T-code will be opened as below



by following the above steps you can call any ERP Screen using HTML mashup and how to add this mashup in the required screen

      Hi Ahmed rashed ,


      How can we restrict the acess to other t-codes? Because, with this, users are able to insert different transactions in ERP.
