Reuse data in the activity designer 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. About this task 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. Procedure 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 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. 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 the pop-up window.
