This error means your script hit NetSuite’s governance usage limit (e.g., 10,000 units for Map/Reduce). To avoid it:

• Use the right script type:
  For bulk processing, use Map/Reduce instead of Scheduled or User Event scripts. Map/Reduce is designed to break data into small chunks.

• Batch data:
  If processing search results, fetch in pages (e.g., 500 or 1,000 at a time). Use search.runPaged({pageSize: 500}).

• Lightweight map stage:
  Do only lightweight tasks in map() and push data into reduce(). Example: pass record IDs instead of full objects.

• Check remaining usage:

  const remaining = runtime.getCurrentScript().getRemainingUsage();
if (remaining < 200) {
// reschedule or yield
return;
}


• Yield in long loops (Scheduled scripts):
  If stuck with Scheduled scripts, use nlapiYieldScript() (1.0) or break loops manually.

👉 Best Practice: Always design Map/Reduce as stateless batches — if one chunk fails, others continue.
