Sap Rfc Connection Program Id3/30/2021
There we can find the log files with the naming convention as devrfc and the error description can be read from such files.In the next screen, Enter - RFC Destination Name of Destination (could be Target System ID or anything relevant) Connection Type here we choose one of the types (as explained previously) of RFC connections as per requirements.Description This is a short informative description, probably to explain the purpose of connection.
After you SAVE the connection, the system will take you to Technical Settings tab, where we provide the following information: Target Host Here we provide the complete hostname or IP address of the target system. System Number This is the system number of the target SAP system. Click Save In the Logon and Security Tab, Enter Target System information Language As per the target systems language Client In SAP we never logon to a system, there has to be a particular client always, therefore we need to specify client number here for correct execution. User ID and Password preferably not to be your own login ID, there should be some generic ID so that the connection should not be affected by constantly changing end-user IDs or passwords. Please note that this is the User ID for the target system and not the source system where we are creating this connection. Click Save. RFC connection is ready for use Note: By default, a connection is defined as aRFC. To define a connection as tRFC or qRFC go to Menu Bar - Destination aRFC options tRFC options; provide inputs as per requirements. Step 2: Trusted RFC connection There is an option to make the RFC connection as Trusted. Once selected, the calling (trusted) system doesnt require a password to connect with target (trusting) system. Following are the advantages for using trusted channels: Cross-system Single-Sign-On facility Password does not need to be sent across the network Timeout mechanism for the logon data prevents misuse. Prevents the mishandling of logon data because of the time-out mechanism. User-specific logon details of the callingtrusted system is checked. The RFC users must have the required authorizations in the trusting system (authorization object SRFCACL ). Trusted connections are mostly used to connect SAP Solution Manager Systems with other SAP systems (satellites) Step 3: Testing the RFC Connection After the RFCs are created (or sometimes in the case of already existing RFCs) we need to test, whether the connection is established successfully or not. 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. ![]() Authorization Test - It is used to validate the User ID and Password (provided under logon and security tab for the target system) and also the authorizations that are provided. If a test is successful, then the same screen will appear as shown above for the connection test. Sap Rfc Connection Program Id Code Or NotUnicode Test - It is to check if the Target system is a 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. Step 4: What went wrong If somehow the RFC connection is not established successfully, we can check the logs (to analyze the issue) at OS level in the WORK director.
