generate attribute and filename in loop cycle
Goodmorning,
i am new at rapidminer and discovering it as great for ETL and analysis tasks.
Just a question i didn't find documented even if browsing around.
I need to load some csv files, treat these data adding an attribute to corrispondent dataset recorded the name of the file where they come from and then apped it in a unique dataset.
I used loop files operator with read csv, generate attributes subprocess operators and then an append operator.
But in generate attributes right now i am just able to write a fix name for all the files.
I don't know how to reference in generate attributes operator the changing file name for each iteration coming from loop files operator.
Is there any way to do it (for example with any process parameter) directly on Edit List in function descriptions or is there another way?
Thanks in advance
