Appian Community and Appian Academy are being upgraded. From July 24–August 3, the Appian Community will be in read-only mode. During this time, the site will be read-only and user registration will be disabled. We apologize for any inconvenience this may cause, but a more secure, stable, and performant Community experience is coming soon!
The new Appian Community launches August 3, followed by Appian Academy on August 7. During the migration, Appian Community Edition, Appian Academy, Documentation, Certifications, Instructor-led Customer Training, Partner Sales Training & Accreditation, and Forum (for Appian Partners and Customers only) will remain available.
Environment: Appian Community Edition — Site "W1423AIS Acme IT"Data Source affected: W0380 Data Source (MariaDB)Description:I am experiencing errors indicating that multiple tables are missing from my "W0380" data source, which I did not delete or modify manually.Errors observed so far:
On the "W0380AS Vehicle" record type:
"The configured database table is invalid. The AS_VEHICLE table does not exist in the configured data source. Change the database table to continue."
Key details:
I log into this environment regularly; my last login before noticing this issue was about one week prior.I did not perform any manual deletions, renames, or schema changes on these tables.The issue appears to affect more than one table within the same data source (W0380), suggesting a possible environment-wide database issue rather than an isolated table problem.
Request:Please investigate whether the underlying database for this Community Edition environment was reset, migrated, or otherwise affected, and advise whether the missing tables/data can be restored.I'm happy to provide additional screenshots or details as needed

Hi mohamadj925576 ,
Thanks for the detailed information.
Since multiple tables in the same MariaDB data source are reported as missing, and you didn't make any schema changes, it does sound more like an environment-level issue than a problem with a single record type.
A few things you can check while waiting for Appian Support:
AS_VEHICLE
If you're using Appian Community Edition, it's worth noting that Community Edition environments may occasionally be refreshed or reset, and Appian Support is best placed to confirm whether this has happened and whether any recovery is possible.
Hopefully, the support team can verify if the database was reset or migrated and advise whether the missing tables and data can be restored.
