Assume that you are using Data Quality Services (DQS) Cleansing component with large batch in a Microsoft SQL Server 2012 Integration Services (SSIS 2012) or SQL Server 2014 Integration Services (SSIS 2014) package. When you try to execute the package, you may receive the following results:

  • You receive the following error within SSIS package

    OnError,<MachineName>,<UserName>,Data Flow Task - Pass data through DQS,{9C749B1D-3FAF-4E3B-B0B9-C8BA626428F5},{B8582806-2FDB-43EF-8E69-B43E6A375DD2},<Date><Time>,<Date><Time>,0,0x,The value '<StringValue>' in column <ColumnName>' does not fit the current buffer. The value length is 11, but the output column length is 1.
    OnError,<MachineName>,<UserNname>,DQS_Test,{AF400590-A48A-4483-87A0-A5CC5AC8BF09},{B8582806-2FDB-43EF-8E69-B43E6A375DD2},<Date><Time>,<Date><Time>,0,0x,The value '<StringValue>' in column <ColumnName>' does not fit the current buffer. The value length is 11, but the output column length is 1.

    Microsoft.SqlServer.Dts.Pipeline.DoesNotFitBufferException: The value is too large to fit in the column data area of the buffer.
    at Microsoft.SqlServer.Dts.Pipeline.PipelineBuffer.SetString(Int32 columnIndex, String value)
    at Microsoft.Ssdqs.Component.Common.Utilities.ComponentUtility.SetValue(IDTSComponentMetaData100 componentMetadata, PipelineBuffer buffer, Int32 fieldIndex, DataType type, Int32 length, String columnName, Object value) at Microsoft.Ssdqs.Component.DataCorrection.Logic.DataCorrectionComponent.ProcessChunk(ReadOnlyCollection`1 fieldMappings, ReadOnlyCollection`1 records, CorrectedRecordsStatusStatistics& correctedRecordsTotalStatusStatistics)

  • When the package is completed, open up the project generated in DQS client and examine one of the domains. If you sort the domain by value, you may see values from other domains.

Note The failure rate of this issue depends on the batch size. When the size of batch is larger, the failure rate will be larger.

Each new cumulative update for SQL Server contains all the hotfixes and all the security fixes that were included with the previous cumulative update. Check out the latest cumulative updates for SQL Server:


To work around this issue, decrease the batch size to resolve or relieve the issue.
