Rebuilding project shadow files
Each dimension has a shadow file. A shadow file is a listing representation of the dimension hierarchy, with a record for each parent and child pairing in the hierarchy. A shadow file is used to navigate the hierarchy. The user never directly interacts with the shadow file. The shadow data is normally maintained automatically. The rebuilds are available in case there is a problem with the shadow file. A rebuild can be done if data was loaded in a way that could circumvent the shadow building process.
