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)
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.
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.
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
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.
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
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.
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.
the Test Program:
Execute your test program in your SAP
environment. This will initiate the RFC call to the target system.
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.
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.
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.
If performance is a concern, you can conduct
load testing to assess how well RFC handles a high volume of requests.
Handling and Recovery:
Implement error-handling mechanisms and recovery
procedures in your production systems to handle RFC failures gracefully.
· 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.
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
