Add field Last released version

Hi Gopikrishnan 

Thanks for your reply.

Your code doesn't answer exactly my question by was very helpfull.

The JS code to show the last major revision released is : 

var releasedItem = new Item('Document', 'get');
releasedItem.setAttribute('select', 'major_rev');
//aras.AlertSuccess (document.thisItem.getProperty("item_number"));
releasedItem.setProperty("item_number", document.thisItem.getProperty("item_number"));

releasedItem.setProperty("generation", "*");
releasedItem.setPropertyCondition("generation", "like");
releasedItem.setAttribute("orderBy", "generation desc");

releasedItem.setProperty('is_released', '1');

releasedItem = releasedItem.apply();
//aras.AlertSuccess("nb" + releasedItem.getItemCount());
last_rev="";
if (releasedItem.getItemCount() > 0) {
item =releasedItem.getItemByIndex(0);
last_rev = item.getProperty("major_rev");
}
else {
last_rev="";
}
