Diagnosis
The keys for the InfoObjects are numeric. This means the SIDs can begenerated directly from the keys and do not have to be taken from anumber range object. Thus indexing of this table is not necessary.
However, this step is still necessary because there can be numericInfoObjects that have navigation attributes that are not numeric. Thenthe master data table for the InfoObject have to be indexed. For reasonsof consistency, this always occurs within the SID table indexing.
