SAP uses the communications protocol, Remote Function Call (RFC), to interact with external systems.

You need the

sapnwrfc.ini

file to process SAP IDocs or SAP BAPI/RFC functions that facilitate transfer of data when you read from or write to SAP through the SAP IDoc or SAP BAPI/RFC interface.

Create the

sapnwrfc.ini

file and include the necessary connection information and RFC-specific parameters required by the SAP connection type. You can use a DOS editor or WordPad to create the

sapnwrfc.ini

file, so that you can avoid errors commonly introduced by Notepad. Check out Sample sapnwrfc.ini files for connection types to know more about the

sapnwrfc.ini

file samples that you can use for different connection types.

After you create the

sapnwrfc.ini

file, you need to place the

sapnwrfc.ini

file in the agent directory. The agent verifies the

sapnwrfc.ini

file, and then use it for the configured connection.

Placing the sapnwrfc.ini file in the agent directory

You can use the Secure Agent or serverless runtime environment to connect to the SAP system as an RFC client, as follows:

To use a Secure Agent, place the
sapnwrfc.ini
file in the following location:
<Informatica Secure Agent installation directory>\apps\Data_Integration_Server\ext\deploy_to_main\bin\rdtm\
To use a serverless runtime environment, place the
sapnwrfc.ini
file in the following location:
\data2\home\cldagnt\SystemAgent\apps\Data_Integration_Server\ext\deploy_to_main\bin\rdtm\

Ensure the

deploy_to_main\bin\rdtm

directory exists. If it does not, create it and then place the files.

Restart the agent after placing the file in the required directory.

Upgrading from an earlier version

If you are upgrading from an earlier version, you do not need to create an

sapnwrfc.ini

file. The Secure Agent copies the

sapnwrfc.ini

file to the

deploy_to_main\bin\rdtm

directory.

Verifying the sapnwrfc.ini file

When you create a connection, the Secure Agent first verifies if an

sapnwrfc.ini

file exists in the directory. If the

sapnwrfc.ini

file exists, the Secure Agent uses the

sapnwrfc.ini

file. Else, an exception occurs.
