Filter Spec
Use this field to select which property on a form is to be filtered on when calling up a record in context, within a Notify or Prompt action.
This field is designed to be used in conjunction with the Filter Form field. The Filter Form field designates which form is opened. The Filter Spec field designates the criteria to be used in determining what is displayed when that form opens.
You must use the FILTER function in this field.
For example, you design an event handler that requests approval for a new purchase order before the PO is approved. Instead of sending the PO information along with the message, you can set the recipient's Inbox form so that the recipient can click the button to open the Purchase Orders form with the new PO displayed.
