In certain windows, we have a concept of a locator field, which typically acts as a filter on some lists of the current object. Examples are user group's filter on description and several IB windows' filter by date.
In case the page is dropped after a data change, locator fields throw an unexpected warning about loss of data. To avoid this warning on locator fields, you can add a function that enumerates the locator fields, such as the following:
function ignoreModifiedFields(){
return ['START_DTTM']
}
You can include any number of fields in the array, e.g.
return ['FIELD_1', 'FIELD_2', 'FIELD_3']
