Pentaho Action Sequence is an XML file, which defines a workflow of tasks in Pentaho. It is needed to glue together several different Pentaho components that need to interact to achieve a purpose such as creating and e-mailing a report in PDF format.

All the Action Sequence files have the .xaction extension and should be located in the [BISERVER]/pentaho-solutions folder. This folder also stores system configuration and Pentaho solution files. Pentaho solution is a file generated by the Pentaho design tools, such as Pentaho Reporting, Pentaho Schema Workbench, Pentaho Data Integration.

Action Sequence files can be created using Pentaho Design Studio, a desktop client tool. For more information about this tool, visit http://goo.gl/a62gFV.
