SYMPTOMS

After you install any cumulative update or service pack for Microsoft Office Project Server 2007 that was released in October 2008 or later, the SharePoint Products and Technologies Configuration Wizard fails. Additionally, the following error message logged in the Upgrade.log file:

“Microsoft.Office.Project.Server.Upgrade.ReportingDatabaseUpgrader_12_1_153_0.Upgrade()” The DELETE statement conflicted with the REFERENCE constraint "FK_MSP_TimesheetLine_TaskNameUID". The conflict occurred in database "TaskConsistency_<instance_name>_Reporting", table "dbo.MSP_TimesheetLine", column 'TaskNameUID'. The statement has been terminated. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlCommand.RunExecuteNonQueryTds(String methodName, Boolean async) at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery() at Microsoft.Office.Server.Data.SqlSession.ExecuteScript(TextReader textReader, Int32 commandTimeout) at Microsoft.SharePoint.Upgrade.SPDatabaseAction.ExecuteSql(String sql, Int32 commandTimeout) at Microsoft.SharePoint.Upgrade.SPDatabaseAction.ExecuteSql(String sql)at Microsoft.Office.Project.Server.Upgrade.ReportingDatabaseUpgrader_12_1_153_0.Upgrade() at Microsoft.SharePoint.Upgrade.SPActionSequence.Upgrade()

CAUSE

This issue occurs because of a very specific condition in the reporting database. In a very small number of cases, there may be duplicate records in the reporting database. These duplicate records can cause the SharePoint Products and Technologies Configuration Wizard to fail.

RESOLUTION

Before you install any Project Server 2007 cumulative update or service pack that is released in October 2008 or later, use the following script to check for the condition in the reporting database.

Notes

Only run this detection script one time. If you receive a positive then run the recovery script. Do not run the detection script a second time because it will show a positive again even though there is no longer a problem. If you run the detection script a second time and still get a positive result, it's a false positive and this is by design. The detection script was written to be very sensitive to any indication of the problem that causes the failure. The fix script, however, is pinpointed at fixing the exact problem that causes the failure. If you re-run the detection script, it is possible that there is still some little detail in your database that it's picking, but the fix script will have already fixed the root of the failure.
If you have a default installation of Project Server, the name of the database is named ProjectServer_Reporting. You can also verify the name of the reporting database that is associated with your Project Server site through the SharePoint Central Administration Web site.
