Evaluating Condition in a Workflow

Evaluating Condition in a Workflow

Use Condition in link conditions to evaluate the result of a decision condition expression.
The following figure shows a workflow with link conditions using Condition:
Condition Variable Example
The workflow contains the following tasks: Start, Command, Decision, Email if the decision evaluates to false, and Command if the decision evaluates to true.
The decision condition expression for the FileExist Decision task is $Check_for_file.Status = SUCCEEDED. The mapping includes two link conditions: $FileExists.Condition = False triggers the email task and $FileExists.Condition = True triggers the Command task, Process_the_File.
When you run the workflow, the Integration Service evaluates the link condition and returns the value based on the decision condition expression of the FileExists Decision task. The Integration Service triggers either the email task or the command task depending on the Check_for_File task outcome.
