如何使用 SuiteScript 2.0 重新安排 Netsuite 中的调度脚本

Question

I want to reschedule the schedule script , when the schedule script usage before hitting the governor limits. schedule script in Netsuite has 10,000 units. In SuiteScript 1.0 version, rescheduling is acheived by "nlapiScheduleScript() api " but in SuiteScript 2.0 version how to reschedule the script.

help me to achieve this,thanks in advance.

The N/task and N/runtime modules have what you're looking for. You'll use N/task to do the rescheduling, and N/runtime to get the current script info.

Without your exact code I can't give a very specific example, but your scheduled script will end up looking generally something like:

/**
 * @NApiVersion 2.x
 * @NScriptType ScheduledScript
 */
define(['N/task', 'N/runtime'], function(task, runtime) {

    /**
     * Reschedules the current script and returns the ID of the reschedule task
     */
    function rescheduleCurrentScript() {
        var scheduledScriptTask = task.create({
            taskType: task.TaskType.SCHEDULED_SCRIPT
        });
        scheduledScriptTask.scriptId = runtime.getCurrentScript().id;
        scheduledScriptTask.deploymentId = runtime.getCurrentScript().deploymentId;
        return scheduledScriptTask.submit();
    }

    function execute(context) {

        // Do stuff...

        while(...) {
            // Do processing in loop

            // Check remaining usage and reschedule if necessary
            if (runtime.getCurrentScript().getRemainingUsage() < 100) {
                var taskId = rescheduleCurrentScript();
                log.audit("Rescheduling status: " + task.checkStatus(taskId));
                return;
            }
        }
    }

    return {
        execute: execute
    };
});

Answer 2

It seems like scheduledScriptTask.submit() is returning null.

var taskId = rescheduleCurrentScript();

taskId above returns null when logged. Is it possibly a bug in NetSuite side?

Answer 3

The accepted answer is good for occasional yields. In addition to this if you know you are going to often breach the governance limits you may want to consider a Map/Reduce script instead as it has yielding/resuming built in.
