Uploading XML File to SAP ABAP Internal Table

In the previous post I have share exporting or downloading SAP ABAP Internal Table to XML File, but how about the vice versa? Hence, i will explain it as well in 3 similar simple stages:

  1. Prepare your XML File
    For this example, i will use the following XML
  2. Create Transformation:
    
    <?xml version="1.0" encoding="utf-8"?>
    <ROOT>
    <purchase_doc>
    <purchase_no>6000000025</purchase_no>
    <item_no>00010</item_no>
    <changed_on>2015-02-05</changed_on'>
    <material_no>100-100</material_no>
    <stor_loc/>
    </purchase_doc>
    <purchase_doc>
    <purchase_no>6000000026</purchase_no>
    <item_no>00010</item_no>
    <changed_on>2015-02-05</changed_on>
    <material_no>100-100</material_no>
    <stor_loc/>
    </purchase_doc>
    </ROOT>
    
    

    1. Go to tcode STRANS or XLST_TOOL
    2. Create an X XSLT Program Transformation
    3. Copy and Modify the following source code as template
    4. <xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:sap="http://www.sap.com/sapxsl" version="1.0">
        <xsl:output encoding="UTF-8indent="nomethod="xml" version="1.0"/>
        <xsl:strip-space elements="*"/>

        <!-- custom -->
        <xsl:template match="/">
          <asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
            <asx:values>
              <IEKPO>
                <xsl:apply-templates select="//<purchase_doc>"/>
              </IEKPO>
            </asx:values>
          </asx:abap>
        </xsl:template>

        <xsl:template match="<purchase_doc>">
          <item>
            <EBELN>
              <xsl:value-of select="<purchase_no>"/>
            </EBELN>
            <EBELP>
              <xsl:value-of select="<item_on>"/>
            </EBELP>
            <AEDAT>
              <xsl:value-of select="<changed_on>"/>
            </AEDAT>
            <MATNR>
              <xsl:value-of select="<material_no>"/>
            </MATNR>
            <LGORT>
              <xsl:value-of select="<stor_loc>"/>
            </LGORT>
          </item>
        </xsl:template>
        <!--End Custom-->

      </xsl:transform>

  3. Complete your Program

    1. Create a Data Type/Structure/Table Type based on your XML File data
    2. Create the internal table in your ABAP Report
      DATA: it_out TYPE STANDARD TABLE OF <YOUR_DATA_TYPE>.
            wa_out TYPE <YOUR_DATA_TYPE>.
    3. Insert, modify and perform the following FORM.
    form F_XML_IMPORT .
    * Table for the XML content
    DATA: it_xml       TYPE STANDARD TABLE OF char2048.
    
    
    DATA: it_result_xml TYPE abap_trans_resbind_tab,
          wa_result_xml TYPE abap_trans_resbind.
    
    DATA: gs_rif_ex     TYPE REF TO cx_root,
          gs_var_text   TYPE string.
    
    * Set XML File Location
    DATA p_file_name type string.
    p_file_name = "Your_XML_File_Location".
    
    * Get the XML file
    CALL METHOD cl_gui_frontend_services=>gui_upload

    ENDIF.
    
    * Fill the result table with a reference to the data table.
    * Within the XSLT stylesheet, the data table can be accessed with

      CATCH cx_root INTO gs_rif_ex.

    endform.                    " F_XML_IMPORT
