With FME Desktop I'd like to write a text file with a dynamic filename, consisting of the date of today and a guid. I know how to create both parameters (date and guid), but I don't understand how to integrate it into to filename, e.g. 2020-09-02_ABCDEFG123id.txt
The problem about it is that only feature type names can be created dynamically. But the filename has to be chosen when adding the writer, so it cannot be changed depending on the input data. I tried the TXT-, the XML- and the Generic-writer.
