When both SAPCAR and NWRFC have been downloaded, use SAPCAR to unpack the NWRFC SAR archive:
-
Open a command prompt and navigate to the location of the files.
-
Unpack them with a command similar in format to
C:\SAPCAR_721-20010451.EXE -xvf NWRFC_42-20004566.SAR
where the first argument refers to the SAPCAR file and the third one refers to the the NWRFC file. A folder called ‘nwrfcsdk’ is created.
It is not recommended to put the ‘nwrfcsdk’ directory in a user specific directory
(such as the Desktop) as this can sometimes have permission issues. Rather place it
in a more general location such as C:\
-
Add the location of nwrfcsdk\lib to the Path variable in the System variables section of the Environment Variables window.
An environment variable can be set as a System or a User variable. A System variable will allow the SAP connector to work regardless of which user j5 is configured
to run as, whereas a User variable would only be for the user logged in at the time the variable is entered.
