Editing the sapnwrfc.ini File          

The sapnwrfc.ini file contains a DEFAULT section that specifies some global properties, followed by SAP connection information organized into DESTINATION entries. Each destination specifies one particular method of connection between NLINK and SAP.

If you are using the NLINK SAP RFC/BAPI, Query or Transaction CoNNector or IDOC (for sending IDOC to SAP) CoNNectors , and you connect directly to an application server (e.g., not load-balanced, single-sign-on (SSO) or via SNC) then you do not need to edit the sapnwrfc.ini file. You can fill out all the information you need in the appropriate External System Attributes.

If you are using the NLINK RFC Listener CoNNector or IDOC CoNNector (to receive IDOCs from SAP), and  no advanced parameters need to be specified (e.g. not  using SNC or SAPRouter) then you do not need to edit the sapnwrfc.ini file. You can fill out all the information you need in the appropriate External System Attributes.

In all cases you will need one or more destination entries.

Each destination has a number of parameters that indicate how NLINK should find the SAP system. You can have any number of destinations in a single sapnwrfc.ini file, as long as all the destination names are unique.

You will probably need to get some of the parameter information from an SAP system administrator. If the SAP GUI is already installed and has a valid connection set up, you can also usually find the parameters you need there.

Put each destination parameter on its own line with an equals sign (=) between the parameter name and its value. You may include comment lines by starting with ”#” or ”/*” or ”//”. Anything on a line following those markings will be ignored. Include an empty line after each destination section.

The default file provided during the NLINK installation contains documentation about the various connection types and parameters.
