Configuring an Assignment Task

Configuring an Assignment Task

Before you can use an Assignment task to assign a value to a user-defined workflow variable, you must create the workflow variable with an initial value.
  1. Add an Assignment task to the workflow.
  2. Select the Assignment task in the editor.
  3. In the
    Properties
     view, click the
    Assignment
     tab.
  4. In the
    User-defined Variable
     column, select a user-defined workflow variable.
  5. Click the arrow in the Expression column.
    The
    Assignment Expression Editor
     appears.
  6. Enter the value or expression to assign to the variable.
    The
    Functions
     tab lists transformation language functions. The
    Inputs
     tab lists workflow parameters and variables. Double-click a function, parameter, or variable name to include it in the expression.
    Type operators and literal values into the expression as needed.
  7. Validate the expression using the
    Validate
     button.
    Errors appear in a dialog box.
  8. Fix errors and validate the expression again.
  9. Click
    OK
    .
