How To Fix RSDD004 - Activation of aggregate & was canceled (too many tables)

SAP Error Message - Details

• Message type: E = Error

• Message class: RSDD - Message class for data manager

• Message number: 004

• Message text: Activation of aggregate & was canceled (too many tables)

What causes this issue?

For each aggregate your own tables are created in ABAP Data Dictionary
and on the database. All the table names beginning with &V2& are
reserved for these tables.
The already used tables are managed in the catalog of the aggregates
(Table RSDDAGGLGT). The determination of the table name according to
this management table produced the result that the last permitted table
name &V3& has already been used
As table names are reserved for aggregates in the name range 999 it
could be the case that too many aggregates have been defined.

System Response

The creation of aggregate &V1& for InfoCube &V4& is no longer possible.

How to fix this error?

If you have defined a great deal of aggregates, you must first delete
other aggregates. If only a few aggregates have been defined but the
error message appears anyway, then proceed as follows:
Start the transaction again and try to activate aggregate &V1& again,
there could be a buffer problem.
Search in OSS for a note on error message <ZH>RSDD003</>, the problem
may already be known.
Write a problem message. Please include the long text of this error
message in the problem message.

• What is the cause and solution for SAP error message RSDD004 - Activation of aggregate & was canceled (too many tables) ?

  The SAP error message RSDD004, which states "Activation of aggregate & was canceled (too many tables)," typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the activation of an aggregate due to the number of database tables involved. This can happen when the aggregate is too complex or when it references too many underlying tables, exceeding the system's limits.
  Cause:
  
  Too Many Tables: The aggregate you are trying to activate references too many tables, which exceeds the limit set by the system.
  Complex Aggregates: The aggregate may be designed in a way that it pulls data from multiple InfoProviders or involves complex calculations that require numerous joins.
  System Limitations: There may be system-defined limits on the number of tables that can be processed during the activation of aggregates.
  
  Solution:
  
  Simplify the Aggregate: Review the design of the aggregate and try to simplify it. This may involve reducing the number of tables or InfoProviders that the aggregate references.
  Split Aggregates: If possible, consider splitting the aggregate into smaller, more manageable aggregates that can be activated independently.
  Check System Settings: Consult with your SAP Basis team to check if there are any configurable parameters that can be adjusted to allow for more tables during aggregate activation.
  Performance Optimization: Optimize the underlying data model to reduce complexity. This may involve creating additional InfoObjects or restructuring the data flow.
  Use of Composite Providers: If applicable, consider using Composite Providers to combine data from multiple sources without creating overly complex aggregates.
  Consult SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on best practices for aggregate design.
  
  Related Information:
  
  SAP BW Documentation: Review the official SAP BW documentation for guidelines on designing aggregates and best practices.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Performance Monitoring: Use transaction codes like RSA1 (Data Warehousing Workbench) to monitor the performance of aggregates and identify potential bottlenecks.
