[ @RC = ] dbo.bsp_DI_CreateHierarchyFromDimension
@DimensionTableName = N'dimension_table_name' ,
@HierarchyTableName = N'hierarchy_table_name' ,
@ListOfColumns = N'list_of_coloumns' ,
[ @ColumnSeparator = ] N',' ,
@CurrentSiteId = 'current_site_id'
[,[ @IncludeNoneRow = ] N'T' | N'F ]
[,[ @SaveChanges = ] N'T' | N'F ]
