Oracle NetSuite Sync Error: Sync didn't finish successfully! Your login credentials are invalid/expired

Why the Sync Error occurs

There are several possible causes for this error message:

The user credentials being used to connect the sync are incorrect or have expired
The Oracle Netsuite Account is a OneWorld/multi-subsidiary account and the user isn't entering the subsidiary ID in Cashflow360 when setting up the sync
The user credentials being used to connect the sync don't belong to a Oracle NetSuite native Administrator
- NOTE: Not even a "full access" user will be allowed to connect the sync. A native Oracle NetSuite admin's login credentials must be used.
The account has Two-Factor Authentication (2FA) or Token-Based Authentication (TBA) enabled in Oracle NetSuite
- Two-Factor Authentication isn't supported by the sync integration

The solution for this error varies based on the underlying cause.

Incorrect/expired login credentials To update your login credentials in Cashflow360, follow these steps:

Select Settings
Under Sync, select Setup
Select Disconnect
Select Yes to confirm the disconnection
Select Settings
Under Sync, select Setup
Select Connect
Reenter the login credentials
- Be sure to include the subsidiary ID, if applicable
Select Save
- This will start a sync in Cashflow360

Non-admin login credentials Update the sync login credentials to an Oracle NetSuite Administrator's in Cashflow360:

Two-Factor Authentication/Token-Based Authentication Disable 2FA/TBA for the native Oracle NetSuite Administrator role in Oracle NetSuite:

Go to Setup > Users/Roles > Two-Factor Authentication Roles
For the Administrator role, select Not required in the Two-Factor Authentication Required drop-down menu
Select Submit
