Hi Vinisius,
Most applications expect data in a specific format – for example, some require commas in-between field data and some expect tabs. Timestamps can also be formatted differently.
In the case of Generic format vs Birt’s CSV2FXT, the timestamp format actually differs since CSV2FXT expects it the date in yyyy.MM.dd format rather than yyyyMMdd. As such, you should use whatever format is appropriate for the application you are exporting to otherwise you will encounter errors.
Regards.
