How to Apply a Gift Certificate to a Sales Order in NetSuite SuiteScript

To programmatically apply a gift certificate to a sales order, SuiteScript 2.x functions such as record.setSublistValue or record.setCurrentSublistValue should be used. The specific internal IDs for the gift certificate redemption sublist and its fields (e.g., for authorization code and applied amount) should be verified in the NetSuite Records Browser for the current account version. A common approach involves setting the authorization code and the amount to be applied on the relevant sublist line.

An example of how this might be implemented, assuming the correct internal IDs and a record in dynamic or standard mode, is as follows:

javascript
// Assuming 'salesOrderRecord' is a loaded or created record object
// and 'giftCertInternalId', 'giftCertAmount' are defined variables.

// IMPORTANT: The sublist ID 'giftcertredemption' and field IDs 'authcode', 'authcodeapplied'
// are examples from SuiteScript 1.0 and require verification in the NetSuite Records Browser
// for SuiteScript 2.x to ensure correct functionality in your specific environment.
// Sublist lines are typically 0-indexed in SuiteScript 2.x.

salesOrderRecord.setSublistValue({
    sublistId: 'sublist_id_for_gift_certificate_redemption', // e.g., 'giftcertredemption'
    fieldId: 'field_id_for_authorization_code', // e.g., 'authcode'
    line: 0, // Adjust line index as needed; 0 for the first line
    value: giftCertInternalId
});

salesOrderRecord.setSublistValue({
    sublistId: 'sublist_id_for_gift_certificate_redemption', // e.g., 'giftcertredemption'
    fieldId: 'field_id_for_applied_amount', // e.g., 'authcodeapplied'
    line: 0, // Adjust line index as needed; 0 for the first line
    value: giftCertAmount
});

This approach ensures that the gift certificate's authorization code and the amount to be applied are correctly associated with the sales order.
