title: Warning "The OLE DB Source. Outputs[OLE DB Source Output] references an external data type that cannot be mapped to the data flow task datatype"
body: <p>I am new to SSIS and I need proper guidance to solve one problem. I get a warning in SSIS "he OLE DB Source. Outputs[OLE DB Source Output] references an external data type that cannot be mapped to the data flow task datatype. The data flow task type DT_WSTR will be used instead" </p>
  
  <p>Also, this particular integration doesn't run properly and I have to run it manually using the option of "executing package". Is that due to the warning mentioned above?</p>
