• What is the cause and solution for SAP error message KWUI023 - Standard attribute evaluated more than once ?

  The SAP error message KWUI023, which states "Standard attribute evaluated more than once," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when dealing with queries or data modeling. This error indicates that a standard attribute in a query or data model is being evaluated multiple times, which can lead to performance issues or incorrect results.
  Cause:
  
  Duplicate Attributes: The same standard attribute is being referenced multiple times in the query or data model.
  Incorrect Query Design: The design of the query may inadvertently cause the same attribute to be evaluated multiple times due to joins or aggregations.
  Data Model Issues: There may be issues in the underlying data model, such as incorrect relationships or joins that lead to multiple evaluations of the same attribute.
  
  Solution:
  
  Review Query Design: Check the query design in the Query Designer. Ensure that standard attributes are not being included multiple times. Remove any duplicate references.
  Optimize Data Model: Review the data model for any unnecessary joins or relationships that could cause the same attribute to be evaluated multiple times. Simplify the model if possible.
  Use Calculated or Restricted Key Figures: If you need to evaluate the same attribute in different contexts, consider using calculated or restricted key figures instead of directly referencing the standard attribute multiple times.
  Check Aggregation Levels: Ensure that the aggregation levels in the query are set correctly. Sometimes, changing the aggregation level can help avoid multiple evaluations.
