Optional View Technique

If a task UI must display data that the user can review, and if this data is optional, then you can make the view optional.

Using the Optional View Technique

This topic describes how to use the optional view technique.

To use the optional view technique

1. Open the Task Editor for the task UI you must modify.

   For more information, Opening the Task Editor.

2. Add a Siebel operation step using values from the following table:

   Property	Value
   Operation	Query

3. Optional. In the Multi Value Property Window, click the Output Arguments tab, and then add an output argument using values from the following table.

   Property	Value
   Type	Output Argument
   Output Argument	NumAffRows For more information, see Arguments of a Task Step.

   For more information, see Creating an Output Argument on a Task Step.

4. Add a Decision step:
   1. Place this decision step immediately after the step you added in Step 2.
   2. Add a branch using values from the following table.

      Property	Value
      Type	Condition

   3. In the conditional branch, test that the value of the NumAffRows task property is a literal value that equals 0.
   4. Add another branch using values from the following table.

      Property	Value
      Type	Default

5. Add a view step immediately downstream of the decision step.

   This view step displays the optional data.

6. To bypass the optional view, use the condition branch.

Example of the Optional View Technique

An activity field can include instructions. If no instructions exist, then the task UI can skip the view that displays them.
