## Procedure

1. Create a data variable.
2. From Type, select Object.
3. Expand the Advanced options for the Object variable whose data structure you want to replace.
4. From Structure, select Start from Template.  
   Workflow Studio displays the Template field.
5. From Template, select the template containing the template you want to load.
