Task Property and the Property Set

A task property is an object that stores a value that the task UI gets from the Siebel database or gets before or during processing. The following examples describe some of the ways that Siebel CRM can use a task property:

• Pass information between objects. For example, between two steps in a task UI, between a task and a subtask, or between a task and a business service. You define the task property as an input argument or output argument for the step.
• Design a decision branch that uses the value in a task property.
• Use the value in a task property in an expression.

The final value of each task property is available as a separate output argument when a task UI finishes. You can configure Siebel CRM to pass this value to other objects.

• The process property, which is similar to the task property, see Siebel Business Process Framework: Workflow Guide.

How a Task Property Works

A property set is a hierarchical structure that includes task properties, which are multiple sets of name and value pairs. A property set can include these task properties at each level in the hierarchy. Siebel CRM uses the property set to pass data between steps in a task UI.

Figure 12 illustrates how Siebel CRM uses a task property.

Explanation of Callouts

The following steps describe an example of how Siebel CRM uses a task property:

1. Siebel CRM uses a task property to send data to Task Step 1 as an input argument.
2. Task Step 1 uses the data according to the internal configuration for the step.
3. An output argument on Task Step 1 sends data from the step to the task property.
4. An input argument on Task Step 2 brings the data that Task Step 1 uses into Task Step 2, where Siebel CRM can use it according to the internal configuration that is defined for Task Step 2.

Table 7 describes how a task property manages property sets in two different ways.
