The Switch activity checks
if the value of a passed field or variable is equivalent to one of several case
values.
The switch activity behavior is similar to a switch statement in Java.
When creating a switch activity, select a Variable or
Field to check against activity conditions for a matching field
value. When the value passed in this variable or field matches the value defined in the
Condition field of the activity condition, the workflow progresses
through that activity condition.
注:
Condition activities run as the user whose actions
match the conditions the workflow was waiting for and advances the workflow.
Results
The variable or field selected in the Variable or
Field activity variable determines the possible result values.
Input variables
The following variables determine the behavior of the activity.
表 : 1. Switch activity input variables
Field
Description
Type
Select Variable or Field as the
type of value to check against available conditions. This selection sets the label
and available options for the other field.
Variable or Field
Select the source of the value compared against the switch activity conditions.
The field label and available options depend on the Type
selection.
Variable: select any service catalog variable.
Field: select any field from the
Table defined in the workflow properties.
States
The activity state tells the workflow engine what to do with the activity.
表 : 2. Switch activity states
State
Description
Executing
The workflow engine knows to start the onExecute function
of the activity.
Waiting
The workflow engine ignores the activity until a specific event to restart
the activity is fired.
Finished
The activity finished running. See the result value for the outcome of the
activity.
Cancelled
This activity, or the workflow that contains this activity, was
canceled.
Error
A JavaScript error occurred. Review the logs for error details.
Example
You can create a switch activity that sets different field values on an incident based on
the Assignment group of the incident record.図 : 1. Switch activity example
The Field selected is the incident Assigned
to field.図 : 2. Switch activity Field
If the value of the Assigned to field of the workflow-triggering
incident is Service Desk or Field Services,
the workflow populates values on the incident record before continuing. If the
Assigned to value is Hardware, the workflow
continues without populating any field values.
Condition type (Standard, Else, or Error) is used. For more information, see Manage workflow activity conditions.図 : 3. Hardware group condition
