Description

The transformation in question, DEMO_ST_VALUE, shows the mapping of elementary ABAP data types for date, time, and time stamp to XML and back.

<?sap.transform simple?>
<tt:transform
  xmlns:tt="http://www.sap.com/transformation-templates">
  <tt:root name="DATE"/>
  <tt:root name="TIME"/>
  <tt:root name="DATETIME1"/>
  <tt:root name="DATETIME2"/>
  <tt:template>
    <Date_and_Time>
      <Date>
        <tt:value ref="DATE"/>
      </Date>
      <Time>
        <tt:value ref="TIME"/>
      </Time>
      <DateTime1>
        <tt:value ref="DATETIME1"/>
      </DateTime1>
      <DateTime2>
        <tt:value ref="DATETIME2"/>
      </DateTime2>
    </Date_and_Time>
  </tt:template>
</tt:transform>

Note that tsp is defined with the special type XSDDATETIME_Z from ABAP Dictionary. This type ensures that a special mapping is used for time stamps in packed numbers. This happens by default for the built-in time stamp type utclong.

The transformation is symmetrical.
