Specify operation parameters

In defining the processing for a step, you can choose an operation defined for the queue (work queue or user queue) specified as the step destination. If you choose an operation, the parameters defined for that operation appear on the Parameters tab in the Properties pane. See About operations for information about how operation are used.

To define operation parameters

  1. With the appropriate step selected, click the Parameters tab in the Properties pane.
  2. Select the operation you want to use.
  3. If there are parameters defined for the operation, they appear in the table, listing their name, data type, and access—Read (read from the work item), Write (write to a data field in the work item), or Read/Write (a value that passes from the work item to the operation, where it is processed and then passes back to the work item).
  4. For each parameter, click in the Expression field and specify the expression of the appropriate data type for that parameter.
    • For a Read parameter, the expression can be simple or complex, and can consist of a literal value, or a data field, attachment, or workflow group in the current workflow definition.
    • For a Write or Read/Write parameter, the expression must be the name of a data field defined in the workflow definition. If the data field is an array, you can enter an index in the array, such as Arr[Inx], where Arr is the field name and Inx is an integer expression.
   

TIP In general, operations are defined on queues for work items that will be processed by automated programs. Though less common, operations can also be defined on queues from which participants process work items, including user inboxes.

TIP In the Parameters tab, if the operation you want to use is not listed, it might not be defined for the selected work queue. Check the General tab to see which work queue is selected, or see your workflow administrator to determine the appropriate queue.
