• What is the cause and solution for SAP error message RSBOLAP028 - Maximum number of permitted nodes and leaves exceeded (&1 entries) ?

  The SAP error message RSBOLAP028 indicates that the maximum number of permitted nodes and leaves in a query has been exceeded. This typically occurs in the context of SAP BW (Business Warehouse) when dealing with complex queries or large datasets.
  Cause:
  
  Complex Query Structure: The query may have too many characteristics, key figures, or hierarchies, leading to an excessive number of nodes and leaves.
  Data Volume: The amount of data being processed in the query may be too large, causing the system to exceed its limits.
  Configuration Limits: The system may have predefined limits on the number of nodes and leaves that can be processed in a single query.
  
  Solution:
  
  Simplify the Query: Reduce the complexity of the query by limiting the number of characteristics or key figures. Consider breaking down the query into smaller, more manageable parts.
  Adjust Query Settings: Check the settings in the query designer. You may need to adjust the settings related to the display of data, such as limiting the number of rows returned or using filters to reduce the dataset.
  Increase System Limits: If appropriate, consult with your SAP Basis team to see if the system limits can be increased. This may involve adjusting parameters in the BW system configuration.
  Use Aggregates: If applicable, use aggregates to pre-calculate and store summarized data, which can reduce the load during query execution.
  Performance Optimization: Review the performance of the underlying data model and optimize it if necessary. This may include indexing, partitioning, or other database optimization techniques.
