Setting Actions as Reusable in QTP
You can use thePROPERTIES dialog box to make an action reusable. To do so, in the ACTION PROPERTIES dialog box, check the check box and click OK. A message appears, stating a description of the reusable action.
In the KEYWORD VIEW, the action icon changes to a reusable icon.
Note: You should make an action reusable only after you record and enhance your tests completely. Other testers might start calling the action as soon as you make it reusable.
After you make an action reusable, be sure to consider how changes to your action can affect other tests that call the action.
Note: You can return a reusable action to its non-reusable state. However, changing the state of an action to non-reusable destroys all the calls made to the action.
