Using global variables in transformations

You can use global variables, for example field variables defined in an Event and variables defined in a before Process script, in transformation rules. To be able to use a global variable you must first define it as a root transformation parameter.

Note:

The global variable must be passed to the transformation process. See Passing external parameters

To define a variable as root transformation parameter

1	Right-click the data template panel and select Edit root transformation.

2	Enter the variable as Key and click OK.

Example 19

Using global variables in a transformation rule

In this example you have the following simple Before Process script:

$hello="Hello";
$world="World";

You want to use $hello and $world in a transformation rule:

Attributes and value:
text()	concat($hello, ' ', $world)

To be able to use $hello and $world in this rule, you must define them as root transformation parameters:

Key	Value
$hello
$world
