The advanced set meta data workflow component, Set multiple workflow variables, sets/defines multiple workflow variables. This can be used later in the workflow and also in a template.

The variables can be referenced in XPath expressions with a preceding $-sign.

If you want to create or update a single workflow variable, then you could consider the Set workflow variable component instead.

Please notice the limitation regarding workflow variables and booleans.

The component has these parameters:

1. Name
   The name of the workflow variable, that is to be created or updated. You need to state the variable name without the dollar sign. If you click the magnifying glass you can select any of the predefined variables, Global variables and Tenant variables. It is highly recommended to select the variable as above, but it is possible to set the name of the variable as an XPath expression by clicking the T-icon to the right of the variable name. In that way you can state the name of the variable via an XPath expression like below:
   
   The setup above adds (or updates) the variable, hello with the value, abc.
2.  Value
   The value to assign to the variable. Remember to click the T icon to the right if you want to enter an XPath expression.

You can add more variables/values, by clicking the Add more icon on the right. You can delete a line by clicking on the trash can icon to the right of the line, that you want to delete.
