Syntax


... data="..." ...

Effect

You can specify the following assertions for the content of the attribute data of an element tt:cond:

Assertion	Meaning
initial(node)	Met if the bound ABAP data object is initial
initial(var(variable))	Met if the variable is initial.
dnode	var(variable) = value, value = dnode

The operands of the assertions can be data nodes, variables, or values.

Data nodes node are specified in a special form.

You specify variables in the form var(variable), where variable is a variable or a parameter.

Values value are ABAP values in the associated display format.

You can specify an assertion as a list of more than one of the above assertions, separated by commas. An assertion of this type is met if all assertions in the list are met. Within the list, every data node may appear only once.

Example

The element X is considered during serialization only if the ABAP data object bound to ROOT is 11.

<tt:transform
  xmlns:tt="http://www.sap.com/transformation-templates">
  <tt:root name="ROOT"/>
  <tt:template>
    <tt:s-cond data="ROOT=11">
      <X>
        <tt:value ref="ROOT" />
      </X>
    </tt:s-cond>
  </tt:template>
</tt:transform>

The element X is considered during serialization only if the value of the ABAP data object bound to ROOT1 is initial and the value of the ABAP data object bound to ROOT2 is 22.

<tt:transform
  xmlns:tt="http://www.sap.com/transformation-templates">
  <tt:root name="ROOT1"/>
  <tt:root name="ROOT2"/>
  <tt:template>
    <tt:s-cond data="initial(ROOT1),ROOT2=22">
      <X>
        ...
      </X>
    </tt:s-cond>
  </tt:template>
</tt:transform>
