NS0521 Sync Error in NetSuite Integration

If you see the error:

NS0521 Sync Error: Permission error querying NetSuite for ‘Subsidiary’.

This means the NetSuite integration does not have proper access to subsidiary records.

This error is typically related to permission restrictions in OneWorld or Non-OneWorld NetSuite accounts.

Why the NS0521 Sync Error Happens in NetSuite

The NS0521 error occurs because of permission restrictions tied to how subsidiaries are configured in NetSuite.

The resolution depends on whether your account is:

• A OneWorld account, or
• A Non-OneWorld account.

If the integration role does not have access to subsidiary records, NetSuite blocks the sync.

This is a subsidiary permission issue, not a token formatting or general login error.
