You create overrides on a fragment reference when you edit its properties in the referencing form design. These changes affect only the fragment reference in the current form and do not affect the fragment source file or any other references.You can create fragment reference overrides on properties in the Object, Layout, Border, and Accessibility palettes of the fragment subform. In the Script Editor, you can create overrides for scripts that are defined in the fragment reference subform. The properties you can edit include the tab order, binding, scripts, X and Y positions, and subform properties such as presence and locale.You cannot create overrides on the properties of any objects in the fragment reference, including nested objects such as subform sets or tables. For example, if a fragment reference includes a table, you cannot edit the row shading because row shading is a property of the cells in a table.
