Bindings Tab Components

The Bindings tab includes the following components:

• Variable: Identifies a variable to be bound in the current row. This is a data display and entry field.
• Expression: Specifies an expression to which the current variable is bound. This field can be either a fixed value (for example, 400000), a dataset attribute, a computational formula, or a conditional expression. The expressions can also use other bound variables and thresholds if they are already defined.
• Type: Indicates that the current variable is bound before or after the constraint is matched.
• Binding Definition area: Includes the following fields:
  • Name: Identifies the binding.
  • Binding Type: Indicates that the current variable is bound before or after the constraint is matched. Also indicates whether this is the first time this variable is being bound or whether it has been bound before (Rebind). Options for selection of this drop-down menu include the following:
    • Bind Before: Captures the variable before checking constraints.
    • Bind After: Captures the variable after checking constraints.
    • Rebind Before: Increments or updates a variable that was previously bound; the system does this before checking constraints.
    • Rebind After: Increments or updates a variable that was previously bound; the system does this after checking constraints.
• Expression: Enables you to add or edit a binding expression.
• Comment: Enables you to add or edit optional comments about the selected binding.
• Add: Adds the current variable to the variable list.
• Delete: Deletes the current variable.
• Change: Changes the values stored for the currently selected variable.
• Ok: Applies any modifications to the row.
• Cancel: Cancels any modifications and returns you to the Sequence Scenario Editor.
• Add Variable: Opens the Variable Selector dialog box, in which you can use another binding to define the current binding.
• Add Attribute: Opens the Attribute Selector dialog box, in which you can add attributes from the current dataset for use in defining the current binding.
• Add Threshold: Opens the Threshold Selector dialog box, in which you can add a threshold from the current scenario for use in defining the current binding.
