Specify operation parameters

Some work queue and user queues have one or more operations that you can specify as the step destination. If a selected operation requires parameters, the parameters appear on the Parameters tab in the Properties pane.

To define operation parameters

  1. With the appropriate step selected, select 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 Expression and specify the expression of the appropriate data type for that parameter.

    Choose one of the following options to specify the expression.

    • <undefined> - The expression for this parameter is not defined. It must be defined prior to transfer to the workflow system.
    • <Create parameter_name> - Choose this option to automatically create a field of the appropriate type with the same name as the parameter. This option should be used only if an appropriate field does not already exist.

      NOTE  If the <Create parameter_name> option is not available, a field with the parameter name might already exist, or the parameter name might result in an invalid field name, such as a reserved word.

    • <Build Expression...> - Choose this option to open the Expression Builder dialog box and define an expression using data fields, attachments, system fields, functions, and operators.
    • Existing fields of the matching data type - Choose one of these, as appropriate.
Note:
  • 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.
