ABAP Mapping and Message Mapping

[Former Member]

Hello

I want to do the followig mapping

File - > IDOC

field1 ->field_idoc1

field2 ->field_idoc2

field3 ->field_idoc3

field4 -> (based on an dictionary table in the R/3)

For the first 3 fields I will use message-mapping.

For field4 I heard about ABAP Mapping. Select with the value of field4 in an ABAP Table and response the new value to the mapping back.

Would both mappings in one Interface-Mapping work?

Regards

Hi Christoph,

usually it would be a task for BPM but indeed, u can solve that with a ABAP mapping. Inside that mapping u call a function modul at R/3 (call function 'MyFunction' destination 'MyDest'...).

In one Interface Mapping u can refer as much Mapping Programs as u like. The result of one will be used as source 4 the next.

Christoph , You can call them in sequence within an interface mapping, but cannot call one within another.

To make a lookup, you can write an RFC(which will make the lookup and return the result), call it in the message mapping using a JCO call(inside a user-defined function in message mapping) avoiding two mapping programs

If ur in SP13 , you can call an RFC commn channel from a message mapping to help make the lookup.

Hello Saravana,

the JCO call sounds very good, but I'm not so familiar with Java Coding. Have you, or have someone an example how to call a RFC out of an user-defined function ?

Christoph, There was an article previously available in articles section, now i dont find the link.

I have given a sample code below. You can find lot of sample JCO code provided along with the JCO library that can be downloaded from service.sap.com.

*************************************************

JCO.Repository mRepository;

JCO.Client mConnection = JCO.createClient(

sapClient,

userName,

password,

language,

hostName,

systemNumber );

// connect to SAP

mConnection.connect();

// create repository

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

// Create function

JCO.Function function = null;

IFunctionTemplate ft = mRepository.getFunctionTemplate("Z_TEST");

function = ft.getFunction();

// Obtain parameter list for function

JCO.ParameterList input = function.getImportParameterList();

// Pass function parameters

input.setValue( param1_value , "P_PARM1");

input.setValue( param2_value , "P_PARM2");

JCO.ParameterList tabInput = function.getTableParameterList();

JCO.Table inputTable = tabInput.getTable("T_PARM3");

inputTable.appendRow();

inputTable.setValue("test" , "IDOC");

}

mConnection.execute( function );

String ret = function.getExportParameterList().getString( "P_GEN_NUM" );

mConnection.disconnect();

return ret ;

Hello Saravana ,

thanks for your help, but i guess i got lost.

I created a custumer function "rfc_test01"

public void rfc_test01(String[] a, ResultList result, Container container){

JCO.Repository mRepository;

JCO.Client mConnection = JCO.createClient(

300,

chch,

pas0111,

de,

sapm10a.aa.cust.de,

00 );

....

And added you coding into the body.

1. question:

Do I need to place "JCO.Repository mRepository;" into the field IMPORTS?

2. question:

Is this connection ok?

JCO.Client mConnection = JCO.createClient(

300,

chch,

pas0111,

de,

sapm10a.aa.cust.de,

00 );

3. question:

my function Z_CHA_TEST01 looks like:

import: im_field

export: ex_field

Hi XI SDN Folks,

i have a doubt.

Using JCO , i will export P_GEN_NUM1.

i need to export remaining parameters also.

i need P_GEN_NUM1,P_GEN_NUM2,P_GEN_NUM3,P_GEN_NUM4,P_GEN_NUM5.

i don't like to call BAPI again and again for each field.

String ret = function.getExportParameterList().getString( "P_GEN_NUM1" );

is it possible to do this single Look up?

Please Help. Thanks in Advance
