RFC (Remote Function Call)
- These are Special type of Function Module's which are used to communicate with remote servers.
- The remote servers can be SAP to SAP or SAP to Non-SAP servers.
- To make a function modules as remote enables function modules we have to add some additional properties.

After having started, the RFC server programs must inform the RFC library about all RFC functions that can be called within this server program.

What is difference between RFC and IDOC?
The main difference b/w IDOC and RFC is IDOC runs on ABAP stack, RFC runs on Java stack, so less processing time in IDOC. No need to create sender communication channel in IDOC, for RFC need to create communication channel. IDOC is used for only asynchronous communication, RFC for both sync, async.Aug 22, 2007
What are types of RFC in SAP?
The first version of RFC is synchronous RFC (sRFC). This type of RFC executes the function call based on synchronous communication, which means that the systems involved must both be available at the time the call is made. Transactional RFC (tRFC) and Queued RFC (qRFC).
How does SAP calculate RFC connection?
To check the RFC connection for an SAP System:In the system overview, position the cursor on the SAP System for which you would like to check the connection.Choose SAP System Check Connection Test . If the RFC connection is established, the message Connection to system
When should we use Transactional RFC?
You can use transactional RFCs, for example, for complex processes that require updating of related database tables during different phases in a transaction. Transactional RFC processing ensures that all the planned updates are carried out when the program reaches the COMMIT WORK statement.
What is ALE and EDI in SAP?

Type 3 Connection
This connection type is used to specify connection between ABAP systems. Here, you need to mention the host name and IP address of source system and also the logon information. This is applicable for both type of RFCs, between ABAP systems and external calls to ABAP systems.
Type I Connection
This connection type is used to specify ABAP systems connected to the same data base as the current system. Let us take an example entry name — ws0015_K18_24
Type T Connection
This connection type helps connect destinations to external programs that use the RFC API to receive RFCs. This can be activated using start or registration.
Step 1: Procedure to setup an RFC connection
In the SM59 screen, you can navigate through already created RFCs connection with the help of option tree, which is a menu-based method to organize all the connections by categories.
Step 2: Trusted RFC connection
There is an option to make the RFC connection as ‘Trusted’. Once selected, the calling (trusted) system doesn’t require a password to connect with target (trusting) system.
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.
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. There we can find the log files with the naming convention as “ dev_rfc<sequence no.> ” and the error description can be read from such files.
