How were you able to save the Flat File Connection Manager Editor settings without defining columns? I have a file with Headers and Lines. There are 21 columns for headers and 11 columns for lines. If I let the connection manager define the columns of my flat file automatically it will find 21 but the package fails as soon as it gets to a line row (before it can be evaluated by the conditional split task) since it's finding carriage returns after column11.
Not sure how to get around that. Can you explain, or include a seoncd screen shot of the Flat File Connection Manager Editor column definition screen? Or did you data set happen to have the same number of columns for all rows, regardless of the type of data in the row?
