| + | A Decision Node within a Workflow allows the workflow to branch down different paths based on the outcomes of previous nodes within the workflow stage. Default outcomes are available to test the outcomes of the node that immediately precedes the decision node. The outcomes available will depend on the node that precedes the decision node and may include: | ||
| − | + | :* Failure | |
| − | + | :* Success | |
| − | + | :* No Match | |
| + | :* Expired | ||
| + | :* Task or Authorisation outcomes | ||
| − | + | In addition to these default options, you can also build your own custom expressions using the Custom Expression Builder. Custom Expressions will allow you to evaluate the outcomes of any node that precedes the decision node within the same stage.| | |

| − | + | A Custom Expression consists of one or more tests that evaluate the outcomes of nodes within the current stage. If the tests within the expression are met, that path out of the decision node will be followed. To add a Custom Expression, click on the description box of a connector that exits a Decision Node and in the ''Goto If'' dialog box, select ''Custom Expression'' from the list of outcomes. | |
