ok. got an "advanced" save search question. I assume the answer is no, but I'll ask anyway as I've been wrong before. I have a saved search that only returns a number of internal ID's based on defined parameters. I then want to use the Internal ID's from that search as a criteria for another saved search. Is this possible? Essentially nesting the saved searches.

Yes you can...Its been on the old NS forum...Not sure where its located in the new Oracle forum but its possible:https://community.oracle.com/community/netsuite/users/forum/platform-areas/customization/searches-list-views/363725-buttons-within-a-saved-search
