Simple Transformation from Adobe Form XML document to Dictionary structures

Question

I have an XML document that I am receiving via email (the XML document is generated from an Adobe Interactive form). I would like to write a simple transformation that will map that XML document to a structure and internal table in my ABAP program. I am new to Simple Transformations and I am having trouble working out how to write a simple transformation for this type of XML document. I would prefer to write a custom transformation rather than using the identity transformation (ID). I would appreciate any help you can provide.
Please refer to the below for an example of the XML file.
This maps directly to 2 dictionary structures that exist within our system containing all of the same components. PIM_REQUEST_HDR has a corresponding SAP dictionary structure Y_REQUEST_HDR and PIM_REQUEST_ITEMS has a corresponding SAP dictionary structure Y_REQUEST_ITEMS.
Can anyone help with some instructions or examples of how to create the simple transformation?
Thanks for your help! We are using ECC 6.0
Sample XML to be transformed:
<?xml version="1.0" encoding="UTF-8" ?>

Answer 1

I have solved this one with the help of another collegue.
To simplify, we changed the XML to be as follows:
[code]
<?xml version="1.0" encoding="UTF-8" ?>
<data>
<PIM_REQUEST>
<REQ_HDR>
  <MANDT />
  <REQ_NUM />
  <REQ_DESC>Key required for pricing routines</REQ_DESC>
  <PROC_AREA>SD</PROC_AREA>
  <REQUESTED>2007-07-30</REQUESTED>
  <REQUIRED>2007-08-02</REQUIRED>
  <REQUESTOR>TLCITY</REQUESTOR>
  <MOD_TYPE>SAP Note: Manual Changes</MOD_TYPE>
  <SAPNOTE_NUM>0000000000</SAPNOTE_NUM>
  <SAPMSG_NUM>0000000000</SAPMSG_NUM>
  <TECH_SCRIPT>TS-2498 Pricing Routines</TECH_SCRIPT>
  <REASON>New pricing routines required</REASON>
  <DEV_ENV>ECC6</DEV_ENV>
  <INSTALL_NO>029</INSTALL_NO>
  <BASIS_REL>700</BASIS_REL>
  <REG_STATUS />
  <REJ_REASON />
  <APP_DATE />
  <REJ_DATE />
  <APPROVER />
  <REGISTRATOR />
  <REG_DATE />
  </REQ_HDR>
<KEY_DETAILS>
<DATA>
  <MANDT />
  <REQ_NUM />
  <PGMID>R3TR</PGMID>
  <OBJECT>PROG</OBJECT>
  <OBJ_NAME>RVGHT902</OBJ_NAME>
  <ACCESSKEY />
  </DATA>
<DATA>
  <MANDT />
  <REQ_NUM />
  <PGMID>R3TR</PGMID>
  <OBJECT>PROG</OBJECT>
  <OBJ_NAME>RVGHT901</OBJ_NAME>
  <ACCESSKEY />
  </DATA>
  </KEY_DETAILS>
  </PIM_REQUEST>
  </data>
[/code]
This maps directly to 1 dictionary structure that exists within our system containing all of the same components. PIM_REQUEST has a corresponding SAP dictionary structure Y_REQUEST_HDR which is a deep structure and has within it a structure REQ_HDR and a table KEY_DETAILS.
The corresponding simple transformation we have then used is as follws:
[code]
<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
  <tt:root name="root"/>
  <tt:template>
    <data>
      <PIM_REQUEST>
        <tt:copy ref="root"/>
      </PIM_REQUEST>
    </data>
  </tt:template>
</tt:transform>
[/code]
Alternatively the following 2 options also work:
Option 2:
[code]
<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
  <tt:root name="root"/>
  <tt:template>
    <data>
      <PIM_REQUEST>
        <REQ_HDR>
          <tt:copy ref="root.REQ_HDR"/>
        </REQ_HDR>
        <KEY_DETAILS>
          <tt:loop name="KEY_DETAILS" ref="root.KEY_DETAILS">
            <DATA>
              <tt:copy ref="$KEY_DETAILS"/>
            </DATA>
          </tt:loop>
        </KEY_DETAILS>
      </PIM_REQUEST>
    </data>
  </tt:template>
</tt:transform>
[/code]
Option 3:
[code]
<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
  <tt:root name="root"/>
  <tt:template>
    <data>
      <PIM_REQUEST>
        <REQ_HDR>
          <MANDT tt:value-ref="root.REQ_HDR.MANDT"/>
          <REQ_NUM tt:value-ref="root.REQ_HDR.REQ_NUM"/>
          <REQ_DESC tt:value-ref="root.REQ_HDR.REQ_DESC"/>
          <PROC_AREA tt:value-ref="root.REQ_HDR.PROC_AREA"/>
          <REQUESTED tt:value-ref="root.REQ_HDR.REQUESTED"/>
          <REQUIRED tt:value-ref="root.REQ_HDR.REQUIRED"/>

          <TECH_SCRIPT tt:value-ref="root.REQ_HDR.TECH_SCRIPT"/>
          <REASON tt:value-ref="root.REQ_HDR.REASON"/>
          <DEV_ENV tt:value-ref="root.REQ_HDR.DEV_ENV"/>
          <INSTALL_NO tt:value-ref="root.REQ_HDR.INSTALL_NO"/>
          <BASIS_REL tt:value-ref="root.REQ_HDR.BASIS_REL"/>
          <REG_STATUS tt:value-ref="root.REQ_HDR.REG_STATUS"/>
          <REJ_REASON tt:value-ref="root.REQ_HDR.REJ_REASON"/>
          <APP_DATE tt:value-ref="root.REQ_HDR.APP_DATE"/>
          <REJ_DATE tt:value-ref="root.REQ_HDR.REJ_DATE"/>
          <APPROVER tt:value-ref="root.REQ_HDR.APPROVER"/>
          <REGISTRATOR tt:value-ref="root.REQ_HDR.REGISTRATOR"/>
          <REG_DATE tt:value-ref="root.REQ_HDR.REG_DATE"/>
        </REQ_HDR>
        <KEY_DETAILS>
          <tt:loop ref="root.KEY_DETAILS" name="KEY_DETAILS">
            <DATA>
              <MANDT tt:value-ref="$KEY_DETAILS.MANDT"/>
              <REQ_NUM tt:value-ref="$KEY_DETAILS.REQ_NUM"/>
              <PGMID tt:value-ref="$KEY_DETAILS.PGMID"/>
              <OBJECT tt:value-ref="$KEY_DETAILS.OBJECT"/>
              <OBJ_NAME tt:value-ref="$KEY_DETAILS.OBJ_NAME"/>
              <ACCESSKEY tt:value-ref="$KEY_DETAILS.ACCESSKEY"/>
            </DATA>
          </tt:loop>
        </KEY_DETAILS>
      </PIM_REQUEST>
    </data>
  </tt:template>
</tt:transform>
