The databus allows workflow designers to track the flow of data through an Orchestration
workflow and provides access to output data that can be consumed by other custom activities.  
Data is made available in a workflow when you use activities created with the [Orchestration activity designer](https://servicenow-prod.fluidtopics.net/lSI621J4LB2eqOsYrgn1cQ "The Orchestration activity designer enables a user with either the workflow_admin or activity_creator and workflow_creator roles to construct reusable activities that suit an organization's business needs."). The activity designer provides the ability to specify well defined inputs and outputs for your activities. When you use those activities on the workflow canvas, the outputs appear in the Data tab and are available for use as inputs in subsequent activities.  
Hinweis:  
Orchestration does not filter the data you are given for reuse in the Data tab. You must make sure an activity in the workflow canvas has executed before you consume its output data.

When you drop a custom activity onto the workflow canvas, the system assigns it an index. If
you delete an activity from the canvas and add a new one, the indexes are not reused. This
ensures that you don't accidentally start subscribing to data you did not intend to use. If you
update an activity in the activity designer, the system automatically updates the activity on the
canvas to ensure the data you are subscribing to downstream is not affected.

## Reuse data in the activity designer {#ariaid-title2}

The Data tab in the Workflow Editor lists all custom
activities used in the current workflow that produce data and displays that data for reuse
in other custom activities.

### Vorbereitungen

Roles required: workflow_creator

### Warum und wann dieser Vorgang ausgeführt wird

Activities are categorized by application in this tab and are available for use as
data sources for other activities. The Data tab is a
graphical representation of the workflow Databus, which manages all the temporary
data used by the current workflow.

### Prozedur

1. Drag output variables from an activity in this tab into the inputs of another activity on the workflow canvas to link the activities together.  
   You can use any of the outputs in the structure, regardless of the
   application to which they belong. An index number in parenthesis after the
   activity name provides a unique identifier for the parameters that you use
   as input data in other activities. If you do not name a custom activity,
   the only identifier for that activity in the Data tab
   is the index number. Index numbers indicate the sequence in which custom
   activities were added to the workflow and are not reused. When you drag a
   custom activity onto the workflow canvas, the system adds that activity and
   its output data to the structure. Conversely, if you remove a custom
   activity from the canvas, that activity and its outputs disappear from the
   data list.  
2. Point to an activity to display information about it in a pop-up window.  
   Any output data reused by the activity is listed in the Databus Output field of the pop-up window.
