Suitescript TypeError: rec.selectNewLine is not a function

AI generated answer (using internal Slack threads):

The error

TypeError: rec.selectNewLine is not a function

in SuiteScript usually occurs when you are trying to use the

selectNewLine

function on a record that is not in dynamic mode. In SuiteScript, there are two modes for handling records: standard mode and dynamic mode. The

selectNewLine

function is only available in dynamic mode. If you are loading a record in standard mode, this function will not be available. Here is an example of how to load a record in dynamic mode:

javascript
var record = record.load({
    type: 'salesorder', 
    id: '123', 
    isDynamic: true
});

Once the record is in dynamic mode, you can use the

selectNewLine

function to add a new line to a sublist. Here is an example:

javascript
record.selectNewLine({
    sublistId: 'item'
});
record.setCurrentSublistValue({
    sublistId: 'item',
    fieldId: 'item',
    value: '456'
});
record.setCurrentSublistValue({
    sublistId: 'item',
    fieldId: 'quantity',
    value: '1'
});
record.commitLine({
    sublistId: 'item'
});

In this example, a new line is added to the 'item' sublist, the item and quantity fields are set, and then the line is committed. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
