If you want to create message contents that may change during a process pass, you can use placeholders.
Procedure
Create an object of the Information carrier type, for example, using the E-mail symbol.
Activate the Start tab bar.
Click the object and then Attributes.
You can use placeholders in both the Subject and Text attributes. Model placeholders for changing contents as follows:
$nameofplaceholder.
The name of a variable can contain only the following characters: A...Z, a...z, numbers from 0 to 9, hyphens (-) or underscores (_).
Placeholders must have identical names in all languages, for example, $process in English, German, and all other languages.
Create or open a data flow for the function connected to the information carrier.
In the data flow of the object of the Human task type, connect Subject and Contents with the fields that have the same name as the placeholders in the text.
You have used placeholders to model contents that can change during the process pass.
