This is the error I kept getting.
[Data Conversion 0 - 0 [2]] Error: Data conversion failed while converting column "FirstDetection" (83) to column "FirstDetection" (11). The conversion returned status value 4 and status text "Text was truncated or one or more
characters had no match in the target code page.".
[Data Conversion 0 - 0 [2]] Error: The "Data Conversion 0 - 0.Outputs[Data Conversion Output].Columns[FirstDetection]" failed because truncation occurred, and the truncation row disposition on "Data Conversion 0 - 0.Outputs[Data Conversion Output].Columns[FirstDetection]"
specifies failure on truncation. A truncation error occurred on the specified object of the specified component.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "Data Conversion 0 - 0" (2) failed with error code 0xC020902A while processing input "Data Conversion Input" (3). The identified
component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the
failure.
And this is what I have in the Data Conversion.
