Adding a property to an IDO

You can add properties to IDOs only if you have first checked out the IDO for which you want to create the property. Use the IDOs form to check out the IDO. Once the IDO has been checked out, you can click the New Property button on either the IDOs form or the IDO Properties form to launch the New Property wizard.
  1. Launch the New Property wizard.
  2. On the first page of the wizard, select the type of binding to use for the new property:
    • Bound
    • Derived
    • Unbound
    • Subcollection

    For information about these binding options, see Understanding Properties.

  3. Click Next.
  4. Set the attributes for the type of property you selected:
    Bind To
    (Required, for Bound property types only) Select the table column to which you want the new property to be bound.
    Subcollection IDO
    (Required, for Subcollection property types only) Select the IDO that is to be used as the subcollection for the new property.
    Property Name
    (Required) Provide the name to be used for the new property.

    For bound properties, this field defaults to the table column name, but you can change it.

    Property Class
    (Optional) Select a property class to be used for the new property.
    Data Type
    (Optional) Select the data type to be used for the new property, along with any co-attribute values, such as Length or Decimal place values.

    If a Property Class has been specified, this value, by default, is inherited from the property class and is read-only. To specify other values (and not inherit from the property class), clear the Inherit from Property Class check box.

    Column Data Type
    (Optional) Select the column data type to be used for the new property.

    If a Property Class has been specified, this value, by default, is inherited from the property class and is read-only. To specify a different value (and not inherit from the property class), clear the Inherit from Property Class check box.

    Expression
    (Optional, used only for Derived and Unbound properties) Specify an expression to be used for the values of the new property.

    If a Property Class has been specified, this value, by default, is inherited from the property class and is read-only. To define a different expression (and not inherit from the property class), clear the Inherit from Property Class check box.

    Note: The expression can include "parameterized" values for which actual values are substituted at runtime. These parameterized values must be formatted as a zero-based index of consecutive integers in curly braces ({0}, {1}, and so on). Actual values are then passed in as a comma-delimited list. For more information and examples, see SUBSTITUTE, an event action function in the Application Event System that uses similar logic.
  5. Click Finish.
The New Property wizard creates the property with the attributes you have specified and adds it to the list of properties for the IDO.

You can further define the applicable attributes of the new property using the IDO Properties form. [Reminder: Context-sensitive help is available for all fields/options on that form.]
