Commerce Server Staging (CSS) was unable to export the business data to the source folder you specified for the project. Make sure that the service account for CSS has sufficient database permissions to export the data. For information about granting accounts access to the database, see How to Grant Staging Accounts Access to the Databases. For information about what database access permissions to grant, see What Database Access Permissions Must You Grant to CSS Authentication Accounts?
Make sure that the source folder where you want to put the exported files exists.
