Exercise 7: RFC to WebService to Retrieve ZipCode data

Overview

The purpose of this exercise is to implement a synchronous execution of a webService usingRFC from a R/3 system via XI !s a result of this exercise" you will become familiar with the basic

se#uence of steps to implement a simple interface with XI along with RFC sen$er a$apter an$S%!& receiver a$apter This exercise will also intro$uce import of 'S() $ocuments intointegration repository

Prerequisites

*asic +nowle$ge of XI architecture

Description

! 'ebService that is available at the following site will be invo+e$ from R/3 system using anRFC The input parameter for this webService is a ,ipCo$e-.S an$ it returns informationregar$ing this ,ipCo$e li+e city" county" state" longitu$e an$ latitu$e" etc If an incorrect ,ipCo$eis entere$ an error message is returne$

Exercise steps

0&lease note" as a general rule" all $evelopment an$ configuration ob1ects in XI are C!S2S24SITI52

Step 6 7 S)(

In this exercise" we will $efine a software component version which will house all our

$evelopment ob1ects This is $one in the system lan$scape $irectory -S)( 'e will create a newSoftware Component version 'e will also $efine a technical system an$ business system forthe webService service

In this exercise there is no nee$ to $efine any software

66 'e will be using the &ro$uct as $efine$ before

?ou can go bac+ to the main page by clic+ing :bac+ to Software Catalog;

66@ 'hen you are finishe$ browsing" from the software catalog screen select :SoftwareComponent; from the $rop$own list

66A Select :4ew Component; This will ta+e you to the wi,ar$ for creating a new SoftwareComponent -S'C

66B The pro$uct we will use is calle$ :XI RI8 .S 'or+shop; of ven$or :S!& XI RI8 .S;Select this pro$uct from the $rop$own list Fill out the remaining fiel$s as specifie$below Then clic+ :Create; 4ote after the S'C is create$" you will see a confirmationmessage in a green box at the top of the screen The fiel$s of the wi,ar$ will be reset inor$er to allow you to create another S'C if necessary Clic+ :Cancel; to get out of thewi,ar$

9A3 %n the left si$e of the mapping choose the RFC M *egin mapping an$ this being a re#uest si$e of mapping it only has one fiel$ to mapSave the ob1ect after mapping is $one

9A@ Creat another message map with the name :,ipCo$e=Resp; Since we are not changingthe output from the webService call" the mapping is pretty straight forwar$ The left si$eof the map will be MipCo$esSoap%ut an$ the right si$e of the map will beM


8/14

9AA Since some the names an$ structures are same" we can ma+e use of a mapping featurewherein" the fiel$s with same names an$ similar structure will get mappe$ automatically

To $o this" highlight the top no$es as shown above an$ clic+ on icon at the top of thescreen !ll the fiel$ which have the same name will get automatically mappe$

Save the ob1ect This conclu$es the steps re#uire$ in Integration *uil$er (esign

Step 3 7 (irectory

36 From the Integration *uil$er home page" select :Integration (irectory;39 'e will be creating a new Communication Channel un$er


10/14

3@ !$$ an inboun$ interface in the receiver tab .se F> to pull up values an$ select:,ipCo$e=in; inboun$ interface from your software component version an$ the rightnamespace Save the ob1ect

3A 4ow create a communication channel The communication channel is essentially thephysical connectivity to/from the application system This is where the a$apterconfiguration ta+es place In this case we nee$ to configure the S%!& a$apter to poll fornew files an$ sen$ them to the Integration Server

3A6 2xpan$ your service an$ rightclic+ on :communication channel;4ew 4ame your

communication channel :S%!&=Receiver;

3A9 For the a$apter type" use the F> help an$ select :S%!&;3A3 Specify :Receiver; since the a$apter will be receiving the messages from the IS3A> Specify the following parameters

Transport &rotocol GTT&


11/14

3K The next step is to create a :Receiver !greement; ob1ect This $efines a bin$ing betweenthe communication channel you 1ust create$" an$ the inboun$ interface

3K6 In the left frame" rightclic+ on :Receiver !greement;4ew

3K9 Specify the following parameters Sen$er Service


12/14

36D In the following steps" you will create an :Interface (etermination; ob1ect 4ow that wehave $efine$ a receiver for the message" we nee$ to assign an inboun$ interface" an$ aninterface mapping -if necessary

36D6 In the area :Configuration %verview for Receiver (etermination; at the bottom of yourscreen" hit refresh

36D9 In the column :Receiver -&artner/Service; rightclic+ an$ select :4ew Specific;" in or$erto create a new interface $etermination ob1ect

36D3 ?ou are now in the screen :2$it Interface (etermination; In the section :Configure$inboun$ interfaces; select the following using F> help 'hen you are $one" please savethe Interface (etermination ob1ect Inboun$ interface ,ipCo$e=in Interface mapping ,ipCo$e=Re#Resp

366 Finally you will create a :Receiver !greement; ob1ect This will allow you to assign areceiver communication channel to the receiver service/interface you have chosen

3666 8o bac+ to the main screen for your receiver $etermination In the area :Configuration%verview for Receiver (etermination; at the bottom of the screen" hit :Refresh;

3669 In the column :Receiver (etermination -Communication Channel; right clic+ an$ select:4ew Specific;

3663 In the screen :2$it Receiver !greement;" for the fiel$ :Receiver Communication Channel;use the input help -F>" an$ select the communication channel :S%!&=Receiver; Savethe Receiver !greement

369 8o bac+ to the main receiver $etermination screen an$ refresh ?our configuration isnow complete an$ activate your ob1ects
