    Question Mapping Process

    Hello to everyone:

    I'm have 2 questions ?:

    How can I aggregate another columns? For example, if I have a txt file with 4 columns, and I need show another two columns, like the sum of two columns or whatever process.

    How can use the JavaScript language?

    I'm have to set a constraint in my ETL process, and I don´t know how do it with JS application. The constraint is found all the data that is 1 file but isn't in another file and the oppoiste way, can anyone help me with this?

    Thanks in advance!

    Regards

    Gonzalo.

    For 1 use a calculator step or JavaScript step.

    For 2... You're probably better off using one of the merge steps or stream lookups, I don't see it happening easily with javascript.

    Regards,
