Effect

These ST statements can be used to limit parts of templates for execution in serializations or deserializations:

All template elements specified within the tt:serialize element are only respected in serializations. All the template elements specified within the tt:deserialize element are only respected in deserializations.

Example

The following Simple Transformation serializes a structure and deserializes to an internal table:

tt:transform
  xmlns:tt="http://www.sap.com/transformation-templates">
  tt:root name="ROOT1"/>
  tt:root name="ROOT2"/>
  tt:template>
    X
      tt:serialize>
        Y
          tt:value ref=".ROOT1.COL1" />
        /Y>
        Y
          tt:value ref=".ROOT1.COL2" />
        /Y>
        Y
          tt:value ref=".ROOT1.COL3" />
        /Y>
      /tt:serialize>
      tt:deserialize>
        tt:loop ref=".ROOT2">
          Y
            tt:value/>
          /Y>
        /tt:loop>
      /tt:deserialize>
    /X>
  /tt:template>
/tt:transform>

The following ABAP program can call the transformation:

DATA xml_string TYPE string.

DATA: BEGIN OF struc,
        col1 TYPE i VALUE 1,
        col2     TYPE i VALUE 2,
        col3 TYPE i VALUE 3,
      END OF struc.

DATA itab TYPE TABLE OF i.

CALL TRANSFORMATION ...
  SOURCE root1 = struc
  RESULT XML xml_string.

CALL TRANSFORMATION ...
  SOURCE XML xml_string
  RESULT root2 = itab.

After deserialization, the internal table contains three lines with the values of the structure components.
