Hi kurt,
there is a tool (very similar to Dwaynes one), which has the functionality to report the data lineage.
You can find a brief example here >> http://www.luetzkendorf.eu/download/getsetuniverse/eFashion_v125_20100207_181430.xls
The sheet ‘dependents_eFashion’ contains the lineage analysis for the universe eFashion. For all objects the used tables and columns will be shown. Additionally the objects containing @functions have a reference pointing to the origin objects.
