LIBNAME Statement Syntax for SAP

LIBNAME libref R3 <options>;
libref
specifies a valid SAS name that serves as an alias to associate SAS with the SAP tables and view. It is any SAS name when you are assigning a new libref.
R3
explicitly specifies the R/3 library engine.
options
names one or more options honored by the R/3 engine, delimited with blanks.
The SAP LIBNAME statement assigns a library and allows the SAP engine to establish the connection to the SAP system. The SAP system checks the logon information submitted in the LIBNAME statement. The checked information includes the values for user, password, language, and client.
A user specifies a LIBNAME statement for the engine, and then can use that libref throughout SAS, wherever a libref is valid.
