This action allows you to update the current item on which the action is running. It gets configured in a similar way as they are in the Add List Item action.
Saving your Work
It is important to note that you must hit OK and Save at all levels of the Custom action in order for your individual actions to be saved. Changes to the custom action are committed only on the ‘Save’ button click on the main custom action new/edit page (AddEditSettings.aspx). When user opens any pop-up and changes anything (like edit action, add action etc.), those are not immediately saved to the settings.
