Connecting SAP in Ruby on Rails
Try downloading nwrfcsdk library from sap and follow instructions mentioned in Readme to perform the installation. Use function Module like ENQUEUE_READ to perform remote call as below −
#!/usr/bin/env ruby
require 'sapnwrfc'
require 'rubygems'
conn = SAPNW::Base.rfc_connect(:client => '800',
:sysnr => '01',
:lang => 'EN',
:ashost => 'hostname',
:passwd => 'pw',
:trace => 0,
:user => 'username')
sm12 = Hash.new
# lookup the dictionary definition of an Function Module
fds = conn.discover("ENQUEUE_READ")
# create an instance of a Function call
func = fds.new_function_call
func.GUNAME = ""
func.invoke
cnt = func.NUMBER
if 1000 < cnt
puts "more than 1000 entries"
end
conn.closeIn case you are running JRuby, you can use SAP Java Connector to connect to RFC enabled BAPI’s and Function module. Note down following points about SAP Java Connector SAP JCo −
