IDoc as a flat file...

Question

I want to read a flat file that is an IDoc and post it as a XML after necessary conversion...So i wanted to know what are the feasible ways to read the flat file thats an IDoc?

Answer 1

Your flat file is of fixed lenght format or tab delimited I believe. Get the flat file data into an internal table. Study the IDOC structure in transaction WE30. & according populate the idoc segemnts from the internal table value..
For ABAP to XML conversion..Create XSLT & the extraction program..
Create XSLT:
In transaction SE80 browse menu Workbench -> Edit Object. In the popup window enter XSLT Program name (e.g. ZXSLT) and click on create button.
Enter the following code into the editor..
<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
<!xsl:output encoding="utf-8" indent="yes"/>
<xsl:template match="D2CXML">
<PurchaseOrders>
<xsl:apply-templates/>
</PurchaseOrders>
</xsl:template>
<xsl:template match="item">
<PONO>
<xsl:attribute name="no">
<xsl:value-of select="EBELN"/>
</xsl:attribute>
<PORDNO>
<xsl:apply-templates select="EBELN"/>
</PORDNO>
<Vendor>
<xsl:apply-templates select="LIFNR"/>
</Vendor>
<PurchaseOrg>
<xsl:apply-templates select="EKORG"/>
</PurchaseOrg>
<PurchaseGrp>
<xsl:apply-templates select="EKGRP"/>
</PurchaseGrp>
<xsl:apply-templates select="X-MLSTRUCT"/>
</PONO>
</xsl:template>
<xsl:template match="X-MLSTRUCT">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="X-MLSTRUCT/item">
<Product>
<ItemNo>
<xsl:apply-templates select="EBELP"/>
</ItemNo>
<Material>
<xsl:apply-templates select="MATNR"/>
