• What is the cause and solution for SAP error message /IWBEP/CM_V4_RUNTIME001 - Filter expression is too complex - Building ABAP select option fails ?

  The SAP error message /IWBEP/CM_V4_RUNTIME001 indicates that the filter expression used in an OData service is too complex for the system to process. This typically occurs when the filter criteria specified in an OData query exceed the limits set by the system, either in terms of the number of conditions or the complexity of the expressions.
  Causes:
  
  Complex Filter Expressions: The filter expression may contain too many logical operators (AND, OR) or nested conditions.
  Large Number of Select Options: If the query includes a large number of select options or parameters, it can lead to complexity.
  Data Volume: The amount of data being queried can also contribute to the complexity, especially if the query is trying to filter on multiple fields with extensive conditions.
  Inefficient Query Design: The way the OData service is designed may lead to inefficient queries that are difficult for the system to process.
  
  Solutions:
  
  Simplify the Filter Expression: Review the filter criteria and try to simplify it. Reduce the number of conditions or break down complex expressions into simpler ones.
  Limit the Number of Select Options: If possible, limit the number of select options being used in the query. Consider using pagination or other methods to reduce the data volume.
  Optimize the OData Service: Review the OData service implementation to ensure it is optimized for performance. This may involve adjusting the underlying ABAP code or the way the service is structured.
  Use Server-Side Filtering: If applicable, implement server-side filtering to reduce the amount of data processed on the client side.
  Check System Limits: Consult SAP documentation or your system administrator to understand the limits imposed by your SAP system regarding filter expressions and adjust your queries accordingly.
  
  Related Information:
