BAPI programing

[Former Member]

Hi All,

Please let me know what the topics of java like Core Java, JSP or Servlets that are used in BAPI programing.

Thanks in advance,

Sriram.

Hello,

There are something called as JCO Function Calls that can be used from java to call BAPI or rfc.

<a href="http://www.huihoo.org/openweb/jco_api/com/sap/mw/jco/JCO.Function.html">Class Documentation</a>

<a href="http://www.sapdevelopment.co.uk/java/jco/jco_callfunc.htm">Java Program</a>

Hope this information is useful.

Correct... Java apps can call BAPI objects in SAP systems. But BAPI objects are built using SAP's own language - ABAP/4.

hi here is the sample code..

it depends on your application ..(basic application need only core java) but you want to see the output in web then you need jsp or servelets.

import com.sap.mw.jco.*;

/**

*/

public class TutorialBapi2 extends Object {

JCO.Client mConnection;

JCO.Repository mRepository;

public TutorialBapi2() {

try {

// Change the logon information to your own system/user

mConnection =

JCO.createClient("001", // SAP client

"<userid>", // userid

"****", // password

null, // language

"<hostname>", // application server host name

"00"); // system number

mConnection.connect();

mRepository = new JCO.Repository("ARAsoft", mConnection);

}

catch (Exception ex) {

ex.printStackTrace();

System.exit(1);

}

JCO.Function function = null;

JCO.Table codes = null;

try {

function = this.createFunction("BAPI_COMPANYCODE_GETLIST");

if (function == null) {

System.out.println("BAPI_COMPANYCODE_GETLIST" +

" not found in SAP.");

System.exit(1);

}

mConnection.execute(function);

JCO.Structure returnStructure =

function.getExportParameterList().getStructure("RETURN");

if (! (returnStructure.getString("TYPE").equals("") ||

returnStructure.getString("TYPE").equals("S")) ) {

System.out.println(returnStructure.getString("MESSAGE"));

System.exit(1);

}

codes =

function.getTableParameterList().getTable("COMPANYCODE_LIST");

codes.setRow(2);

codes.deleteRow();

codes.deleteRow(5);

codes.appendRow();

codes.setValue("XXXX", "COMP_CODE");

codes.setValue("Does not exist", "COMP_NAME");

codes.appendRows(2);

codes.setValue("YYYY", "COMP_CODE");

codes.setValue("Does not exist either", "COMP_NAME");

codes.nextRow();

codes.setValue("ZZZZ", "COMP_CODE");

codes.setValue("Nor does this", "COMP_NAME");

for (int i = 0; i < codes.getNumRows(); i++) {

codes.setRow(i);

System.out.println(codes.getString("COMP_CODE") + '\t' +

codes.getString("COMP_NAME"));

}

}

catch (Exception ex) {

ex.printStackTrace();

System.exit(1);

}

try {

codes.firstRow();

for (int i = 0; i < codes.getNumRows(); i++, codes.nextRow()) {

function = this.createFunction("BAPI_COMPANYCODE_GETDETAIL");

if (function == null) {

System.out.println("BAPI_COMPANYCODE_GETDETAIL" +

" not found in SAP.");

System.exit(1);

}

function.getImportParameterList().

setValue(codes.getString("COMP_CODE"), "COMPANYCODEID");

mConnection.execute(function);

JCO.Structure returnStructure =

function.getExportParameterList().getStructure("RETURN");

if (! (returnStructure.getString("TYPE").equals("") ||

returnStructure.getString("TYPE").equals("S") ||

returnStructure.getString("TYPE").equals("W")) ) {

System.out.println(returnStructure.getString("MESSAGE"));

}

JCO.Structure detail =

function.getExportParameterList().

getStructure("COMPANYCODE_DETAIL");

System.out.println(detail.getString("COMP_CODE") + '\t' +

detail.getString("COUNTRY") + '\t' +

detail.getString("CITY"));

}

}

catch (Exception ex) {

ex.printStackTrace();

System.exit(1);

}

mConnection.disconnect();

}

public JCO.Function createFunction(String name) throws Exception {

try {

IFunctionTemplate ft = mRepository.getFunctionTemplate(name.toUpperCase());

if (ft == null)

return null;

return ft.getFunction();

}

catch (Exception ex) {

throw new Exception("Problem retrieving JCO.Function object.");

}

}

public static void main (String args[]) {

TutorialBapi2 app = new TutorialBapi2();

}

}

HI Sriram

You can write a BAPI using just Core JAVA,

BAPI's are Nothing but a RFC Which has certain Business Functionality....

By RFC I mean--Remote Enabled Function Module...

And for Writing an RFC you just need to have the BASIC PROGRAMMING Knowledge (Core JAVA)...

Cheers:-)
