English Orphan baseline prevents Project Server 2010 report publishing queue to complete its job. In our environment it was caused by sudden disconnection of either client or SQL server during the publish command. I search arround internet and found following discussion on orphan baseline : http://social.technet.microsoft.com/Forums/projectserver/en-US/f4d638ad-003e-421c-85d9-7ed5d7fda029/project-server-2007-error-24006-reportingprojectchangemessagefailed-insert-statement-conflicted . The solution suggested by that discussion is:``` delete from MSP_TASK_BASELINES where MSP_TASK_BASELINES.PROJ_UID =’[PROJECT UID]’ AND MSP_TASK_BASELINES.TASK_UID NOT IN ( select TASK_UID from dbo.MSP_TASKS where PROJ_UID =’[PROJECT UID]‘ )
