These values then will appear in file name also - ie. YYMMDD_RED.csv, YYMMDD_YELLOW.csv, YYMMDD_GREEN.csv - assuming colour is my column here that i want to split records into separate files, many records being red, yellow, and green.
As an aside, previous attempts to FTP I used FTP repository to specify credentials to put files on FTP. Is it possible to set this via contexts? - which can be set by values at database/file. I was slightly bemused when it came to password, as it didn't seem feasible to type in a context variable in here.
