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.

NetSuite blocks the sync when the connected role cannot query subsidiary data.

Why the NS0521 Sync Error Happens in NetSuite

The NS0521 error typically occurs due to subsidiary permission restrictions in NetSuite.

The resolution depends on whether your NetSuite account is:

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

If the integration role or bundle is misconfigured, NetSuite prevents the Workspace from accessing subsidiary data.

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