You use the tabs of the Data Load Settings dialog box to determine how data values are manipulated during data loads:
Data Load Values—Change data values as they are loaded (including adding to and subtracting from the values and flipping the signs of the values).
Clear Data Combinations—Clear existing data values before loading new data values.
Header Definition—Define headers in the rules file.
You click the Outline button to associate the rules file with an outline and to populate dimension nodes.
