What is the correct way to set a multiselect value on suitescript 2.1?

AI generated answer (using internal Slack threads):

To set multiple values on a Multiselect field using SuiteScript 2.1, you can use an array of IDs for the values you want to select. Here is an example:

javascript
rec.setValue({
    fieldId: theFieldId, 
    value: [1,3]
})

Please note that the array should contain the internal IDs of the values you want to select. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
