TRANSFORMATION ABAP : Error accessing the ref. node

[former_member715026]

Hi all,

With this Transformation :

 <?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates" xmlns:ddic="http://www.sap.com/abapxml/types/dictionary" xmlns:def="http://www.sap.com/abapxml/types/defined">
  <tt:root name="ROOT" type="?"/>
  <tt:root name="CRPROD_FILE" type="ddic:ZTT_XML_CROF"/>
  <tt:template>
    <tt:loop ref=".CRPROD_FILE">
      <CRPROD_FILE>
        <FNAME tt:value-ref="CROF_FIC.FNAME"/>
        <ZLOGID tt:value-ref="CROF_FIC.ZLOGID"/>
        <ZNBPROD tt:value-ref="CROF_FIC.ZNBPROD"/>
        <PROD_ORDER>
          <AUFNR tt:value-ref="CROF_HD.AUFNR"/>
          <GSTRP tt:value-ref="CROF_HD.GSTRP"/>
          <GLTRP tt:value-ref="CROF_HD.GLTRP"/>
          <GLTRI tt:value-ref="CROF_HD.GLTRI"/>
          <MATNR tt:value-ref="CROF_HD.MATNR"/>
          <MENGE tt:value-ref="CROF_HD.MENGE"/>
          <MENGE1 tt:value-ref="CROF_HD.MENGE1"/>
        </PROD_ORDER>
      </CRPROD_FILE>
    </tt:loop>
  </tt:template>
</tt:transform>

And this File in input :

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<CRPROD_FILE>
<FNAME>FILE_TST.xml</FNAME>
<ZLOGID>TSTID</ZLOGID><ZNBPROD>1</ZNBPROD><PROD_ORDER><AUFNR>900001005861</AUFNR><GSTRP>20200713</GSTRP><GLTRP>2020717</GLTRP><GLTRI>2020714</GLTRI><MATNR>101061</MATNR><MENGE>10</MENGE><MENGE1>10</MENGE1></PROD_ORDER></CRPROD_FILE>

We got the "Error accessing the ref. node 'CRPROD_FILE'".
What is wrong ?

There are two possible solutions, depending on what you want to achieve:

• Either you want the element <CRPROD_FILE> to occur several times in the XML file, in that case your XML structure is missing a root element (<CRPROD_FILES> or <DATA> for instance).
• Or you want the element <CRPROD_FILE> to occur only once in the XML file, so you should put <CRPROD_FILE> outside the loop. And maybe you need to do other changes in your transformation.

Hi Sandra,
Its the second time you help me, thanks for your reply !
I changed it with the second way ZST_XML_CROF structure (instead of ZTT_XML_CROF table)

<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates" xmlns:ddic="http://www.sap.com/abapxml/types/dictionary" xmlns:def="http://www.sap.com/abapxml/types/defined">
  <tt:root name="ROOT" type="?"/>
  <tt:root name="CRPROD_FILE" type="ddic:ZST_XML_CROF"/>
  <tt:template>
    <CRPROD_FILE>
        <FNAME tt:value-ref="CRPROD_FILE.CROF_FIC.FNAME"/>
        <ZLOGID tt:value-ref="CRPROD_FILE.CROF_FIC.ZLOGID"/>
        <ZNBPROD tt:value-ref="CRPROD_FILE.CROF_FIC.ZNBPROD"/>
        <PROD_ORDER>
          <AUFNR tt:value-ref="CRPROD_FILE.CROF_HD.AUFNR"/>
          <GSTRP tt:value-ref="CRPROD_FILE.CROF_HD.GSTRP"/>
          <GLTRP tt:value-ref="CRPROD_FILE.CROF_HD.GLTRP"/>
          <GLTRI tt:value-ref="CRPROD_FILE.CROF_HD.GLTRI"/>
          <MATNR tt:value-ref="CRPROD_FILE.CROF_HD.MATNR"/>
          <MENGE tt:value-ref="CRPROD_FILE.CROF_HD.MENGE"/>
          <MENGE1 tt:value-ref="CRPROD_FILE.CROF_HD.MENGE1"/>
        </PROD_ORDER>
      </CRPROD_FILE>
  </tt:template>
</tt:transform>

and now i got the "Error accessing the ref. node 'CROF_FIC.FNAME'".

How to declare this Node ?

I think the issue is more about the starting point of VALUE-REF. You should start from the root using a dot. And you could reduce the size of the names with tt:ref:

<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates" xmlns:ddic="http://www.sap.com/abapxml/types/dictionary" xmlns:def="http://www.sap.com/abapxml/types/defined">
  <tt:root name="ROOT" type="?"/>
  <tt:root name="CRPROD_FILE" type="ddic:ZST_XML_CROF"/>
  <tt:template>
    <CRPROD_FILE tt:ref=".CRPROD_FILE">                <!-- =============== here -->
        <FNAME tt:value-ref="CROF_FIC.FNAME"/>
        <ZLOGID tt:value-ref="CROF_FIC.ZLOGID"/>
        <ZNBPROD tt:value-ref="CROF_FIC.ZNBPROD"/>
        <PROD_ORDER tt:ref="CROF_HD">                  <!-- =============== and here -->
          <AUFNR tt:value-ref="AUFNR"/>
          <GSTRP tt:value-ref="GSTRP"/>
          <GLTRP tt:value-ref="GLTRP"/>
          <GLTRI tt:value-ref="GLTRI"/>
          <MATNR tt:value-ref="MATNR"/>
          <MENGE tt:value-ref="MENGE"/>
          <MENGE1 tt:value-ref="MENGE1"/>
        </PROD_ORDER>
      </CRPROD_FILE>
  </tt:template>
</tt:transform>
