BODS problem with flat files and folder rights

Hello,

we have a problem loading a flat file with BODS.

The flat file is located on the job server (Win-Server) under the path D:\flatfile\flatfile.txt

When we execute the job we receive the following error: "Cannot open file D:\flatfile\flatfile.txt. Check its path and permissions."

Which user needs the rights to access the folder/file: the user which runs the job-server/bods-service or the user which uses Data Services Designer and executes the job?

Is the path correct?

Thanks in advance.
