Objective
The purpose of this task is to create a Communication System for the integration scenario Bank Integration with File Interface (1EG).
This communication system will later be used in the communication arrangement and will reference the communication user created in the previous task.
Business Scenario Explanation
In this scenario, you are setting up:
Bank Integration with File Interface (1EG)
In SAP S/4HANA Cloud, the technical setup typically requires:
a Communication User
a Communication System
a Communication Arrangement
In Task 13, you created the communication user.
In Task 14, you now create the communication system and link that previously created communication user for inbound communication.
The communication system represents the external or technical integration partner definition used in the scenario.
Important Notes
Always replace ###### with the last 6 digits of your group number.
Use the exact values shown in the task.
Do not change capitalization, underscores, or spacing.
The communication user assigned in this task must be the one created in the previous step:
1EG_COMM_USER_######
Required Values
Use the following values exactly as shown in the task image.

Example
If your suffix is 000013, then the values become:
System ID = 1EG_SYSTEM_000013
System Name = Bank Integration with File Interface
Host Name = DUMMY
Inbound Communication User = 1EG_COMM_USER_000013
Step 1: Open the app "Communication Systems"
From the SAP S/4HANA Cloud launchpad:
Log in to SAP S/4HANA Cloud.
Use the search bar or app finder.
Search for:
Communication Systems
Open the app.
Explanation:
This app is used to create and maintain technical communication systems for integration scenarios.
Because the task explicitly asks to create a Communication System, this is the correct app.
Step 2: Start creating a new Communication System
Inside the Communication Systems app:
Click:
New
Explanation:
This starts the creation of a new communication system record.
Step 3: Enter the System ID
In the communication system creation screen, enter:
System ID = 1EG_SYSTEM_######
Example
If your suffix is 000013, enter:
1EG_SYSTEM_000013
Explanation:
This is the technical ID of the communication system.
It must exactly match the task requirement.
Step 4: Enter the System Name
In the System Name field, enter exactly:
Bank Integration with File Interface
Explanation:
This is the descriptive name of the communication system and must be entered exactly as provided.
Step 5: Enter the Host Name
In the Host Name field, enter exactly:
DUMMY
Explanation:
For this simulation, the host is not a real productive endpoint.
The task explicitly requires the placeholder value DUMMY.
Step 6: Maintain the inbound communication user
Locate the section for:
Users for Inbound Communication
Then:
Click Add or select the entry field/value help
Choose the communication user created in the previous task:
1EG_COMM_USER_######
Example
If your suffix is 000013, select:
1EG_COMM_USER_000013
Explanation:
This is a critical link between the communication user and the communication system.
Without assigning the previously created communication user, the communication system setup is incomplete.
Step 7: Verify the inbound user assignment
After adding the inbound communication user, confirm that the selected user is:
1EG_COMM_USER_######
Explanation:
This confirms that the system will use the correct technical user for inbound communication in the later communication arrangement.
Step 8: Review all entered values
Before saving, check the following:
System ID = 1EG_SYSTEM_######
System Name = Bank Integration with File Interface
Host Name = DUMMY
Users for Inbound Communication = 1EG_COMM_USER_######
Explanation:
This review helps avoid validation issues caused by incorrect naming, missing underscores, or selecting the wrong communication user.
Step 9: Save the Communication System
Click:
Save
Explanation:
This finalizes the creation of the communication system.
Without saving, the communication system will not exist for the next task.
Step 10: Verify the saved Communication System
After saving, confirm that the communication system exists and displays the correct values:
1EG_SYSTEM_######
Bank Integration with File Interface
Host = DUMMY
inbound user = 1EG_COMM_USER_######
Explanation:
This confirms the system is successfully created and ready for the communication arrangement setup in the next step.
Expected Result
After this task is completed successfully:
the communication system exists,
the system ID matches the required naming pattern,
the system name is correct,
the host name is DUMMY,
the previously created communication user is assigned for inbound communication, the system is saved successfully.
