The document provides steps to upload data from a flat file to SAP Business Intelligence 7.0. It involves creating infoobjects and an infoarea to model the data, creating a data source for the flat file, building an infocube as the data target, defining transformation rules to map source fields to target fields, loading the data into the persistent staging area, and creating a data transfer process to load the staged data into the infocube. The process loads the flat file data in full into the BI system for analysis.
