I have a simple data flow with an oledb source and an oledb target. The data gets directly loaded from the source to the target with no components in between. I've added 2 new columns to the target. I've included 2 existing columns from the source which I did not need when I first wrote the package. I mapped the columns (named exactly the same). In the advanced editor I can preview the data from the source. The columns exist, but I do not see data for these 2 columns. All the data for the previously mapped columns exist.
Anyone seen this?
