SAP Message RSRV721 - SID hierarchy structure successfully rebuilt

DESCRIPTION
Using SIDs from characteristic values and hierarchy nodes, the hierarchystructure is stored in this table. In principle, this table saves thesame information as the hierarchy table (Hierarchy Table :- Thehierarchical relationships of the characteristic values are stored inthis table if external hierarchies are used for the characteristic.)
Since only SIDs, and not characteristic values or hierarchy nodes, canbe stored in aggregates and InfoCubes, the analysis of the data usingthis table is more effective and quicker.
This table is also referred as I-Table or Inclusion Table.
