Add XML header?

Hi Shamly,

you can achieve that very smart with a second, non parsing ABAP mapping:

-use fm ECATT_CONV_XSTRING_TO_STRING to convert the source to string,

- search for "<?Siebel-Property-Set EscapeNames="false"?>"

- concatenate the  both header and the xml payload

- use fm ECATT_CONV_STRING_TO_XSTRING to convert the string to result (XSTRING)

just a view lines,

Regards,

Udo

my suggestion is a simple java mapping and use normal string functions to achieve the result

Hi Shamly,

You are on right path.

Use your graphical mapping (for complex lookup and other logic) after that use another Java Mapping ( to add <?  ?> line) in Operational Mapping.

Use this bolg to develop Java Mapping /people/carlosivan.prietorubio/blog/2007/12/21/implementing-a-java-mapping-in-sap-pi

Hope this code will help you

import java.io.*;

import java.util.*;

import com.sap.aii.mapping.api.*;

public class DynamicMapping implements StreamTransformation {

    private Map param;

    public void setParameter(Map param) {

        this.param = param;

    }

    public void execute(InputStream in, OutputStream out) throws StreamTransformationException {

        try {

          byte[] b = new byte [in. available ()]; //  in.available() is in square brackets

                        in.read(b);

          StringBuffer input = new StringBuffer( new String(b));

                        /*note         "   '  '   "       in double Quotes  we can have single Quotes.

                        /Here we are inserting <?Siebel-Property-Set EscapeNames='false'?>  after <?xml version="1.0" encoding="UTF-8"?> i.e after ?> */

          input.insert(input.indexOf("?>")+2, "<?Siebel-Property-Set EscapeNames='false'?>");

                       out.write(b.toString().getBytes()); 

        } catch (IOException ex) {

           ex.printStackTrace();

        }

    }

}

Hi,

I guess you can also do this by using a simple XSLT mapping after your grphical in the operation mapping. The cod efor the same is as given below:

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<!-- Add the your desired field -->

<xsl:output method="xml" indent="no" omit-xml-declaration="no"

Siebel-Property-Set EscapeNames="false"/>

<!-- Identity Transform - copy the source XML to the output without any changes -->

<xsl:template match="node() | @*">

<xsl:copy>

<xsl:apply-templates select="node() | @*"/>

</xsl:copy>

</xsl:template>

</xsl:stylesheet>

Warm Regards,
