Cool NetSuite trick I discovered today that not everybody might know: When you’re viewing a search and inline editing is turned on, if you click on a field value in one of the columns and Shift or Control + click down the column, you can bulk edit all the values of that field for the items selected. You can also use it to bulk delete records with the settings icon to the left. Bonus tip: to enable inline editing on item searches, you have to include Type in your criteria.

Very nice, knew about deleting but I didnt' realize you could also add values

No way, thats awesome.

Please be careful, there is no UNDO. You can only edit certain fields and certain records types.
