    Exclamation How I know that txt input file is empty?

    I read many txt input files. When the files has rows with data it´s ok. But, when the file is empty, my transformation don´t do anything.

    How I know that a input file is empty (no rows)?

    Isn't that the whole point not to do anything. Your transformation will just quit as the input is empty.

    If you really want to know you could read the file in another transformation and do a group by on it e.g. In the weekly tips there a similar example using a table input to check whether rows are available for processing.
