How to Create HTTP RFC destination between two ABAP systems

 Details:

Create HTTP RFC destination between two SAP systems

Steps:

1.  Go to the transaction SM59.

2. Click on Create as shown in the screenshot.

3. Provide RFC Destination , Connection Type - H , Target URL & ICM Port.. As a good practice for the HTTP ABAP connection always recommended to create a destination with name convention <SID>CLNT<CLIENT_NO>_HTTP. Also, if you want to access some service give the path of the service in path prefix.

4. Click on Logon Security tab and provide target system Client no., Username and Password and Click on Save to Save the RFC destination.

5. Click on Unicode tab. Now a days all the abap systems are the unicode system. So select the UNICODE radio button and Click on Save.

6.  To test connection goto the shown path to test if the target system is reachable. If the test is successful result will be as shown below.

Note:

- Always make sure to use the SYSTEM type user for the RFC destination.

- Never use DIALOG / COMMUNICATION user type in RFC destination, if the system parameter login/password_expiration_time is set then the user password will expire and RFC will fail.

- In some special case scenario SERVICE type user can be used in RFC destination.

- For trust SSL Handshaking Choose SSL => ACTIVE and Certificate List PSE. Also Upload and save the certificate in the same PSE from STRUST.
