Loop Files Operator

How can we transfer data from loop files operator to data to documents operator?
- The nested processes in loop files operator are working fine
- When I connect it to documents to data, I can't select text attribute in its properties, there isn't any option in the dropdown
- Similarly, I can't set role label
Need urgent Help
P.S. - I'm trying out the process mentioned in Chapter 14 of the book - RapidMiner - Data Mining Use Cases and Business Analytics Applications by CRC Press, edited by Markus Hofmann and Ralf Klinkenberg

Hey,
what defintly works, but is maybe not the most elegant solution, is using a Loop collection. Attached is a process showing it.

Hi,
have you tried to use an append operator?
Otherwise could you maybe post your process please?

Hey Martin
Thanks a lot!
Will add it to the process, hopefully no other issues arise.
