Troubleshooting: How to Verify RFC Connection in SAP

How To Check Rfc Connection In Sap

Run transaction Call View Maintenance (SM30) and edit table Definitions for RFC RFC Remote Function Call (RFC) is the standard SAP interface for communication between SAP systems . RFC calls a function to be executed in a remote system. › saphelp_gbt10 › helpdata › content RFC – SAP Documentation – SAP Help Portal Connections (CRMRFCPAR) in the SAP ERP system . Enter a consumer. For more information, see the entries in table Possible Users of R/3 Adapter Functionality (CRMCONSUM) and the RFC destinations.

How to Verify RFC Connection in SAP

You have the choice to designate the RFC connection as “Trusted”. When this option is chosen, the calling system (which is considered trusted) does not need a password to establish a connection with the target system (which is considered trusting).

Here are the benefits of utilizing trusted channels:

1. Facility for logging in to multiple systems with a single sign-on.

2. Eliminates the need to transmit passwords over the network.

3. Includes a timeout feature that prevents unauthorized use of login information.

4. Protects against potential mishandling of login data due to the timeout mechanism.

5. Verifies the specific login details of users from both calling and trusted systems.

The RFC users in the trusting system need to have the necessary permissions (authorization object S_RFCACL). Trusted connections are commonly utilized for connecting with other SAP systems, often referred to as satellites.

How can I verify RFC connections?


1. Position cursor on SAP System in system overview.

2. Choose “SAP System Check Connection Test”.

3. Verify if RFC connection is established.

4. Message confirming successful connection will be shown as “Connection to system &lt,SID&gt, (host &lt,host&gt,) ok”.

Step 3: Verifying the RFC Connection in SAP

Once the RFCs have been set up, it is necessary to verify if the connection has been successfully established.

As shown above we go to SM59 to choose the RFC connection to be tested and then we expand drop down menu – ” Utilities->Test-> “. We have three options:

Connection test -> This attempts to make a connection with the remote system and hence validates IP address / Hostname and other connection details. If both systems are not able to connect, it throws an error. On success, it displays the table with response times. This test is just to check if the calling system can reach the remote system.

Authorization Test is a process used to verify the User ID, Password, and authorizations assigned to a target system. When this test is successful, it will display the same screen as shown above during the connection test.

Unicode Test is conducted to determine whether the Target system is Unicode or not.

Remote Logon –> This is also a kind of connection test, in which a new session of the target system is opened, and we need to specify a login ID and Password (if not already mentioned under ‘Logon and Security’ tab). If the user is of type ‘Dialog’ then a dialog session is created. To justify the successful connection test, output will be the response times for the communication packets, else error message will appear.

To check the RFC (Remote Function Call) connection in SAP, you can use a tool called transaction SM59. This tool allows you to create and manage these connections within the SAP system.

When you need to establish communication between different systems or components in SAP, such as connecting an application server with a database server, you can use RFC connections. These connections enable data exchange and allow programs running on one system to call functions or access data on another system.

The transaction SM59 provides a user-friendly interface for creating and maintaining these RFC connections. It allows you to define various parameters like target host, service number, login credentials, and other settings required for establishing the connection. By using this tool, you can ensure that your RFC connections are properly configured and functioning correctly.

How to Troubleshoot RFC Connection in SAP

If somehow the connection is not established successfully, we can check the logs (to analyze the issue) at OS level in the ‘WORK’ director. There we can find the log files with the naming convention as “dev_rfc ” and the error description can be read from such files.

Displaying RFC in SAP: How is it done?

To check the RFC connection in SAP, you can follow these steps:

1. Start by calling transaction ST03 to open the Workload Monitor.

2. In the Workload tree, select the specific instance and period that you want to analyze.

3. Navigate to Analysis Views and choose RFC Profile from the options available.

4. Select the desired RFC profile for analysis.

After completing these steps, the system will display the requested workload in its usual output area.

How can I obtain a list of RFCs in SAP?

To check the RFC connection in SAP, you can use TCODE SM59. This transaction code allows you to view all the RFC destinations. By accessing SM59, you can ensure that your RFC connections are properly set up and functioning correctly.

By using TCODE SM59 in SAP, you can easily access and manage these defined RFC destinations. This helps in verifying if the connections are established successfully or if there are any issues that need attention.

1. TCODE SM59 is used to check RFC connections in SAP.

2. An RFC connection allows different systems within SAP to communicate with each other.

3. Using SM59 helps verify if the defined connections are working properly or require troubleshooting.

Using SM59 in SAP: A Guide

To check the RFC connection in SAP, follow these steps:

1. Go to transaction SM59.

2. Choose Create.

3. Enter a name and description for the connection.

4. Select the required connection type (G or H).

5. Under Technical Settings, you can make various entries depending on your requirements.

In the Logon/Security section of Technical Settings, you have the option to make different entries based on the chosen connection type. This allows you to configure specific logon and security settings for your RFC connection.
