• What is the cause and solution for SAP error message RSL_UI041 - Join link &1 creates duplicate key figure ?

  The SAP error message RSL_UI041, which states "Join link &1 creates duplicate key figure," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when you are working with queries or data models that involve joins between different data sources or tables. This error indicates that the join condition you are trying to create results in duplicate key figures, which can lead to ambiguity in the data model.
  Cause:
  
  Duplicate Key Figures: The join condition you are trying to establish includes key figures that are not unique across the joined tables. This can happen if both tables contain the same key figure name, leading to confusion in the data model.
  Incorrect Join Logic: The join logic may not be correctly defined, causing the system to interpret the key figures as duplicates.
  Data Model Design: The design of the data model may not be optimal, leading to overlapping key figures across different data sources.
  
  Solution:
  
  Review Key Figures: Check the key figures in both tables involved in the join. Ensure that they are uniquely defined and do not have the same name or meaning.
  Rename Key Figures: If you find that there are duplicate key figures, consider renaming them in one of the data sources to avoid conflicts.
  Adjust Join Conditions: Review and adjust the join conditions to ensure that they are correctly defined and do not lead to ambiguity.
  Use Aggregation: If applicable, consider using aggregation functions to combine key figures in a way that avoids duplication.
  Data Model Optimization: Re-evaluate the overall data model design to ensure that it is structured in a way that minimizes the risk of duplicate key figures.
