NetSuite: How to disable "new" button on a linked record in netsuite using suitescript

Question

We have customer records in NetSuite CRM module with additional custom records linked to the customer record. We have a custom field on customer record "customer status".

Screenshot

Based on customer status we want to disable new custom record (in this case new service record) button. I am able to use beforeLoad script to disable button on main customer record but similar approach fails when I try to disable button associated with linked record.

/**
* @NApiVersion 2.0
* @NScriptType UserEventScript
*/
define(["N/log", "N/ui/serverWidget"], function(log,ui) {
    function disableNewCaseButton(context){
        if (context.type == context.UserEventType.VIEW){
            var customerStatus = context.newRecord.getValue({"fieldId" : "custentitycustomer_status"});
        if (customerStatus !== 1){
            var newButton = context.form.getButton({
                id: 'newrecrecmachcustrecordso_customer_name'
            })
            try{
            newButton.isDisabled = true;
        }
        catch(e){
            log.debug({
                title : "error",
                details: e
            });
        }

        }
        return;
    }
}
    return {
        beforeLoad: disableNewCaseButton
    }
});

Answer 1

I don't believe there is any API supported way to do this.

If you want to resort to DOM hackery, you could use a client script to hide it:

document.getElementById("newrecrecmachcustrecordso_customer_name").style.display = "none";

Keep in mind that there is no guarantee this won't break in a future NetSuite updates.

Another approach could be to leave the button, but use a Workflow or Script on the linked record to prevent it from saving if the customer status is not valid.

Answer 2

Set the custom record Access Type=Use Permission List. Then on the Role configuration, assign the custom record permission to the Role with Access=View.

View access is lower than Create so the user with this role will be able to select but the “New” option will not be available in the dropdown selection.
