OVRDBF is to override the your database data to other file for some temporary time, other file may be the same file or different file. if you want to override your data to some temp place then you should mention that which file data you want to override(file) and where you want to keep your data(to file).

Answer / henry

without File name we cannot use OVRDBF adn its a mandatory
field. Also remember that the file which you used in OVRDBF
also must be present in the system. Else your RPG pgm will
not compile...Generaly if the file is multi member file
(some companies used to store they yearly/monthly
transactions in diff members) and if you want to access
specific member then it's a great deal.
