Go to Transaction SM59 (Display and Maintain RFC Destinations). From the menu bar, click Create. Enter the RFC objective, association type, portrayal, and afterward press Enter. Select the Registered Server Program radio-button, enter the program ID, door host, and passage administration.In the SM59 screen, you can explore through currently made RFCs association with the assistance of choice tree, which is a menu-based strategy to coordinate every one of the associations by classifications.

Click the 'Make' button. In the following screen , Enter -RFC Destination - Name of Destination (could be Target System ID or anything significant)Association Type - here we pick one of the kinds (as made sense of beforehand) of RFC associations according to necessities.Depiction - This is a short educational portrayal, likely to make sense of the reason for association.The most effective method to Configure and Test RFC Connection in SAP - SM59After you'SAVE'the association, the framework will take you to 'Specialized Settings' tab, where we give the accompanying data:Target Host-Here we give the total hostname or IP address of the objective framework.Framework Number - This is the framework number of the objective SAP framework.In the 'Logon and Security' Tab, Enter Target System data

Language - according to the objective framework's language

Client - In SAP we never logon to a framework, there must be a specific client generally, subsequently we really want to determine client number here for right execution.Client ID and Password - ideally not to be your own login ID, there ought to be some conventional ID with the goal that the association ought not be impacted by continually evolving end-client IDs or passwords. For the most part, a client of type 'Framework' or 'Correspondence' is utilized here. Kindly note that this is the User ID for the objective framework and not the source framework where we are making this association.

Click Save. RFC association is prepared for use

Note: By default, an association is characterized as aRFC. To characterize an association as tRFC or qRFC go to Menu Bar - > Destination aRFC choices/tRFC choices ; give inputs according to prerequisites. To characterize qRFC, utilize the exceptional choices tab.

Trusted RFC association

There is a choice to make the RFC association as 'Trusted'. When chosen, the calling (trusted) framework doesn't need a secret key to interface with target (trusting) framework.Following are the benefits for utilizing confided in channels:

Cross-framework Single-Sign-On office

Secret key needn't bother with to be sent across the organization

Break instrument for the logon information forestalls abuse.

Forestalls the misusing of logon information in light of the break component.

Client explicit logon subtleties of the calling/believed framework is checked.

The RFC clients should have the expected approvals in the confiding in framework (approval object S_RFCACL).Trusted associations are generally used to associate SAP Solution Manager Systems with other SAP frameworks (satellites)

1.     RFC Destination Setup:

·         Log in to the SAP system where you want to configure the RFC.

·         Use the transaction code SM59 to access the RFC destination configuration screen.

·         Create a new RFC destination or modify an existing one to define the target system you want to communicate with. Provide details such as the system type, connection parameters, and logon credentials.

2.     Authorization and User Mapping:

·         Ensure that the user specified in the RFC destination has the necessary authorizations to execute the remote function modules on the target system.

·         Implement user mapping if needed, especially when the user ID on the source system differs from the target system.

3.     Testing the Connection:

·         Within the RFC destination configuration, use the "Connection Test" button to check if the connection to the target system is successful. This confirms that the basic network connectivity is working.

4.     RFC Function Module Selection:

·         Determine which remote function module you want to execute on the target system. You will need to specify this function module when testing the RFC.

Testing RFC:

1.     Create a Test Program:

·         In your SAP system, create a test program (e.g., ABAP report) that will initiate the RFC call. This program will typically contain code to call the remote function module using the CALL FUNCTION statement.

2.     Invoke the RFC:

·         In your test program, use the CALL FUNCTION statement to invoke the remote function module on the target system. Pass any necessary input parameters as required by the function module.

3.     Capture and Handle Results:

·         After the RFC call, capture the results or data returned by the remote function module. Handle any exceptions or errors that might occur during the RFC call.

4.     Execute the Test Program:

·         Execute your test program in your SAP environment. This will initiate the RFC call to the target system.

5.     Check Log and Error Handling:

·         Review the log files or error messages generated during the RFC call. These logs can help you diagnose and troubleshoot any issues that may arise.

6.     Monitor the Target System:

·         On the target system, you can monitor RFC calls and their execution. Use tools such as transaction SMQ1 for qRFC or SM58 for tRFC to check the status of queued or failed RFCs.

7.     Verify Data Exchange:

·         Ensure that the data exchanged between systems is accurate and complete. Verify that the remote function module on the target system performed the expected actions.

8.     Performance Testing (Optional):

·         If performance is a concern, you can conduct load testing to assess how well RFC handles a high volume of requests.

9.     Error Handling and Recovery:

·         Implement error-handling mechanisms and recovery procedures in your production systems to handle RFC failures gracefully.

10. Documentation:

·         Thoroughly document the RFC configuration, the test program, and any issues encountered during testing. This documentation will be valuable for ongoing maintenance and troubleshooting.

Testing the RFC Connection

After the RFCs are made (or now and again on account of previously existing RFCs) we really want to test, regardless of whether the association is laid out effectively.As displayed above we go to SM59 to pick the RFC association with be tried and afterward we extend drop down menu - "Utilities->Test->… ". We have three choices:Association test - > This endeavors to make an association with the far off framework and consequently approves IP address/Hostname and other association subtleties. On the off chance that the two frameworks can't interface, it tosses a mistake. On progress, it shows the table with reaction times. This test is simply to check in the event that the calling framework can arrive at the distant framework.

Approval Test - > It is utilized to approve the User ID and Password (gave under 'logon and security' tab for the objective framework) and furthermore the approvals that are given. In the event that a test is effective, a similar screen will show up as displayed above for the association test.Unicode Test - > It is to check in the event that the Target framework is a Unicode or not.The most effective method to Configure and Test RFC Connection in SAP - SM59Distant Logon - >This is likewise a sort of association test, in which another meeting of the objective framework is opened, and we want to determine a login ID and Password (while possibly not currently referenced under 'Logon and Security' tab). On the off chance that the client is of type 'Discourse' an exchange meeting is made. To legitimize the effective association test, result will be the reaction times for the correspondence parcels, else mistake message will show up.

Experience the difference

What turned out badly?

If some way or another the RFC association isn't laid out effectively, we can really look at the logs (to examine the issue) at OS level in the 'WORK' chief. There we can find the log records with the naming show as "dev_rfc" and the blunder depiction can be perused from such documents.
