The advanced set meta data workflow component, Set one workflow variable, sets/defines a workflow variable. This can be used later in the workflow and also in a template in the designer.
The variable can be referenced in XPath expressions with a preceding $-sign.
If you want to create or update multiple workflow variables, then you should consider the Set multiple workflow variables component instead.
Please notice the limitation regarding workflow variables and booleans.
The component has these parameters:
Variable name
The name of the workflow variable, that you want to either create or assign a new value to.
Variable value
The value to assign to the workflow variable. This can either be a constant like above or an XPath expression.
