This typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when working with queries in BEx (Business Explorer) Analyzer or similar tools.
  Cause:
  
  Complex Selections: The selections for the characteristic specified in the error message are too intricate, possibly involving multiple values, ranges, or conditions that exceed the system's processing capabilities.

  Performance Issues: The complexity of the selections may lead to performance issues, prompting the system to restrict the processing of such queries.
  
  Solution:
  
  Simplify Selections: Review the selections made for the characteristic and try to simplify them. This could involve reducing the number of values, ranges, or conditions applied.
  Use Variables: Instead of hardcoding complex selections, consider using variables that can dynamically adjust based on user input or other criteria.
  Check Query Design: Review the design of the query in the BEx Query Designer. Ensure that the selections are necessary and that they are structured in a way that is manageable for the system.
  Default Values: If applicable, check the default values set for the characteristic and see if they can be adjusted to be less complex.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP BW or BI you are using for any known limitations or best practices regarding query design and selection complexity.
