SuiteScript: Adding and Removing IDs from a Multi-Select Field in NetSuite

To add or remove IDs from a multi-select field in NetSuite using SuiteScript, you can manipulate the multi-select field using its internal ID and the respective value(s) you want to add or remove.

Here’s how you can approach both tasks:

1. Add ID to Multi-Select Field:

You would first retrieve the existing values from the multi-select field, append the new ID, and then set the field with the updated array of values.

// Assuming you're in a User Event Script or Suitelet

function addIdToMultiSelect(recordObj, fieldId, newId) {
    // Get current values
    let existingValues = recordObj.getValue({ fieldId: fieldId });

    // Check if existingValues is null or undefined, initialize as an array if needed
    existingValues = existingValues || [];

    // Add the new ID if it's not already in the list
    if (!existingValues.includes(newId)) {
        existingValues.push(newId);
    }

    // Set the updated values back to the field
    recordObj.setValue({
        fieldId: fieldId,
        value: existingValues
    });
}

2. Remove ID from Multi-Select Field:

You would get the current values from the multi-select field, remove the specified ID, and update the field.

// Assuming you're in a User Event Script or Suitelet

function removeIdFromMultiSelect(recordObj, fieldId, removeId) {
    // Get current values
    let existingValues = recordObj.getValue({ fieldId: fieldId });

    // Check if existingValues is null or undefined
    if (existingValues && existingValues.length > 0) {
        // Filter out the ID to remove
        existingValues = existingValues.filter(function(value) {
            return value !== removeId;
        });

        // Set the updated values back to the field
        recordObj.setValue({
            fieldId: fieldId,
            value: existingValues
        });
    }
}

Example Usage:

let recordObj = record.load({
    type: 'customrecord_my_record',
    id: 12345
});

// To add ID 67890 to a multi-select field
addIdToMultiSelect(recordObj, 'custrecord_my_multiselect', '67890');

// To remove ID 67890 from the multi-select field
removeIdFromMultiSelect(recordObj, 'custrecord_my_multiselect', '67890');

// Save the record after modifications
recordObj.save();
