This workflow processes a series of columns in which the first row indicates if the column is mandatory or optional.

If a column is mandatory and contains any missing values, the workflow stops processing, with an error message.

This workflow demonstrates the Java Snippet's "throw Abort("message");

which will return a message to the UI and halt processing.
