We checked on the vmsdev01 under /vmsdb/apps/oracle/admin/VMSDEV01/media/creports/ and the last report was generated on May 14th around 9:00 AM BKK time.
We also checked the vmsdev01 db and it was refreshed from production data on the same date at around 5:30PM which means no VA reports was run after the refresh.
Regent only started the BU Split script on the May 21st which means nobody generated any report between the data refresh and the BU script update.
We are starting to think that something went wrong during the vmsdev01 refresh.
Did your team copied files from /vmsdb/apps/oracle/admin/VMSPRD01/java on VMSPRD01 database server to /vmsdb/apps/oracle/admin/VMSDEV01/java/ on VMSDEV01 database server?
