SAP Message RSDD004 - Activation of aggregate & was canceled (too many tables)

Diagnosis
For each aggregate, separate tables are created in the ABAP Dictionary a
nd in the database. All table names beginning with &V2& are reserved forthese tables.
The tables that are already used are managed in the catalog for the aggr
egates (table RSDDAGGLGT). While determining the table name according tothis management table, the system identified that the last permittedtable name, &V3&, is already assigned.
Since table names are reserved for aggregates in namespace 9999, it is p
ossible that too many aggregates have been defined.

System Response
It is no longer possible to create aggregate &V1& for InfoCube &V4&.

Procedure
If you have defined a large number of aggregates, you must first deleteother aggregates. If you have defined only a small number of aggregates,
and the error message appears, proceed as follows:
Restart the transaction and try to activate aggregate &V1& again; theissue may be due to a buffer problem.
