How the Straight Through Extraction Service Works

The Visibility Services developer specifies data in process data that should be extracted for Visibility Services use.
Based on the Event Schema ID specified in the service configuration, the specified data at that step in the business process will be saved to the Visibility Services fact repository.

Implementing the Straight Through Extraction Service

Use the supplied configuration of the service, StraightThroughExtraction, in your business processes.

The only configuration required for the service is specifying the Event Schema ID to be used for your business process. You specify this in the GPM.

Configuring the Straight Through Extraction Service

You must specify field settings in the GPM.

Field	Description
Config	Select the name of the service configuration from the list. You can use the supplied configuration, StraightThroughExtraction.
eventschemaid	Event Schema ID

Business Process Example

This sample calls the service configuration StraightThroughExtraction with eventschemaid “bi.system.logs”. The service will create an event using the value of eventschemaid as event schema key and all process data under /Processdata/EventAttributes as the event attributes and fire the event. The names under /Processdata/EventAttributes must satisfy the event schema specification.

<process name="sampleStraightThroughExtraction"> 
 <sequence name="main seq"> 
    <assign to="EventAttributes/message">this is message</assign> 
   <assign to="EventAttributes/throwable">this is throwable</assign> 
   <operation name="StraightThroughExtraction"> 
     <participant name="StraightThroughExtraction"/> 
     <output message="StraightThroughExtractionInputMessage"> 
       <assign to="eventschemaid">bi.system.logs</assign> 
       <assign to="." from="*"></assign> 
     </output> 
      <input message="inmsg"> 
       <assign to="." from="*"></assign> 
      </input> 
   </operation> 
   </sequence> 
</process>
