Issue programatically building oledbTransformation.

I get the following validation error when i run a package which contains an OledbTransformation.

The external metadata column collection is out of synchronization with the data source columns.
The column "Param_0" needs to be updated in the external metadata column collection.
The column "Param_1" needs to be updated in the external metadata column collection.

Please advice as to how to add the external columns of oledbTransformation to external meatadata and map them to the input columns programatically using C#.

Please stop starting new threads for the same issue.
