It the current panel is FORM.MAIN then the default object for the RESET command is FORM.
If this option is omitted the current detail variation is reset. An exception to this is when more than one detail variation exists and the current panel is not FORM.DETAIL. In this situation you must specify this option.
If the specified detail variation has not been created yet the number is reduced to the next sequential number following all existing detail variations.
This can be helpful if you make a number of modifications to a detail panel and want to create another with similar changes.
