We just upgraded QB from 2017 to Manufacturing and Wholesale Edition 18.0 and also put our company file on a new server.
Transaction Pro Importer 5.0
Now TPI cannot connect any longer.
We have re-authorised the TPI application and changed the server path being called from the batch file.
The precise error is:
Line: 123 This application is unable to log into this QuickBooks company data file automatically.
The QuickBooks administrator must grant permission for an automatic login through the Integrated Application preferences.
If such permission was already granted, the administrator must revoke permission, save preferences, then grant the permission again.
