Next challenge, anyway to add select option to a sublist column? I have a suitelet that has an item column. Click a button to search for an item which takes you to a second suitelet in a new tab. Enter values, if the item is not found the item is created, and in either case (created / found via search) the item id is returned and set on the line. I'm fine when the item already exists but for newly created items it's causing me a headache... according to help: Record.getCurrentSublistField(options) should give me the field but using that were Record is currentRecord.get() it seems it's not supported.

If your item list is set to source from

item

, then no you cannot add select options. To retrieve the new list of items you would need to reload and let it resource that list

No my list column is not setup that way. I run a search and populate using addSelectOptions. However I'm calling out to a second SuiteLet and on window.close capturing the return value for the item which could be a new item not in the list column. So I'm setting the item column value just fine but it appears "textless" if the item is a new item not already in the list. The problem of course is that to the user the process appears to have failed and never set the column. I know it's correctly seeing and setting the value, that's fine but I seem unable to add the select option. Arguably the currentRecord is not Record and currentRecord does not support getCurrentSublistField so I think I'm sunk.

I've never tried dynamically adding select options to a sublist field after the page is already rendered so I can't be sure if its supported or not. 🤷‍♂️

Thank you for replying (hopefully I don't come across unappreciative). I've been fighting with this for about 90 mins and figured I've exhausted all options and know there are cleverer people than me here Oh well, I finish for the week in 30 mins, starting to feel like a "Monday" problem😁

CurrentRecord.getSublistField is your ss2 option

Thanks for the reply, I did try that to no avail. The answer, actually, was to set the source to inventory_item rather than source teh list manually via a search, which feels the opposite to what I'd imagine doing. Quite bizarre but one to make a mental note of and potentially a future source of frustration if you want to limit the list options to a subset of records.
