Must I save a file to the file cabinet in order to attach it to a PO? NetSuite's habit of overwriting files of the same name to ensure uniqueness is going to mess me around I think. To ensure my attachments are ... themselves, I'm going to have to rename all my files to a gigantic hash I suspect. Currently they are stored in whatever format Coupa is sending them, in a JSON object. Base64 I'm guessing. I'd rather not save them separately unless I have to.
