Your package runs excellently but when I introduced my extra column in your InputFile it produced errors as if OutputBuffer didn't produced the respected value.
I have already updated the destination table, mapping table and mapping_count (in the code).
Is there anything else I should do, I also tried to introduced my new column in CreateNewOutputRows(function) but it gave compile time error as the OuputBuffer didn't have the reference value of this new column.
I would really appreciate if you can help me out, I am stuck in finding the solution of Dynamic Mapping for weeks now. This would be of great help.
