I am running into an error of 'USER_ERROR: Please choose an item to add' when attempting to create a vendor bill which has one line that was not on the associated item receipt. I have a script that returns more descriptive error messages for this scenario, however, it doesn't get called since this error happens prior to the script (beforeSubmit) functions are carried out. Is there no solution here to be able to drill down to more specific error messages? Is this just a NetSuite issue that only NS support can handle?
