  I like to say I know enough VB to be dangerous, and I'm tired of taking a shot in the dark on this.

  I'm getting this error in a VB Script in my SSIS package "Numeric arithmetic causes truncation."  

  Here is the other error info:
  at System.Data.SqlTypes.SqlDecimal.ConvertToPrecScale(SqlDecimal n, Int32 precision, Int32 scale)
   at Microsoft.SqlServer.Dts.Pipeline.PipelineBuffer.SetDecimal(Int32 columnIndex, Decimal value)
   at Microsoft.SqlServer.Dts.Pipeline.PipelineBuffer.set_Item(Int32 columnIndex, Object value)

  Here is the section of VB that it is erring in:  
  
  Public Sub SetPrevYear(ByVal row As Input0Buffer)

    row.AlaeAdtvAllocationAm = row.AlaeUltIncLossAm - row.AlaeCtdPaidAm - row.AlaeIbnrReserveAm
   End If

    End Sub

  I've noted the things I've tried with the 'added  comment.

  I totaled the input data and CurrCaseResv is just over $200,000,000.  CtdNetPd is $2,800,000,000 and CtdNetExp is also just over $200,000,000.  This same process ran with the same data earlier this month in production, not sure why it would be erring when I'm trying to test it.  I didn't change anything in this script, before getting the error.

  Any help you can give to identify what piece of the code is causing the issue would be appreciated.
