The Input Data tool has a "Field Length" option for CSV files. The default is 254 characters. In most cases, this is woefully inadequate. I tend to add several zeroes to the end to prevent truncation. When I don't remember to do this, I get flooded with conversion errors:
"Input Data (2) The field "hours" was truncated in record #38"
I want to set a global default, that I can override per tool, for length so I don't have to do this every time.
