Creation of DataSource for FlatFile Interface in BI 7

Hi Y'all!

Can anyone please give me urgent assistance in creating/defining a DataSource for the FlatFile Scenario in BI 7.0. I've been trying to no avail. I certain I am doing this incorrectly, as such I seek your assistance. Can anyone please be so kind as to give me a step-by-step walkthrough of the specific individual steps (in sequence) in creating/defining DataSources... Also can this be accepted as a character (08-MAY-07)?

Much thanks!
