Can somebody answer this? https://netsuiteprofessionals.com/blog/question/netsuite-suitescript-2-need-to-rename-vendors-while-displaying/

You are trying to edit and change the text on a select field, which is not possible. It nullifies the purpose of a select field.

Ok, is there any other way to show my desired value in the above mentioned select field ?

I don’t remember anything if you can show vendors just by name.
