• What is the cause and solution for SAP error message RS_ADSO_MODEL074 - Index &1 is equal to primary key ?

  The SAP error message RS_ADSO_MODEL074, which states "Index &1 is equal to primary key," typically occurs in the context of SAP BW (Business Warehouse) when working with Advanced DataStore Objects (ADSO). This error indicates that there is an issue with the index configuration of the ADSO, specifically that the index being defined is identical to the primary key of the ADSO.
  Cause:
  
  Index Definition: The error arises when an index is created that has the same fields as the primary key of the ADSO. In SAP BW, the primary key is used to uniquely identify records in the data model, and creating an index that duplicates this can lead to redundancy and inefficiency.
  Modeling Error: It may also occur due to a modeling error where the developer inadvertently tries to create an index that does not add any additional value or performance benefit.
  
  Solution:
  
  Review Index Configuration: Check the index configuration in the ADSO. Ensure that the index being created includes fields that are not part of the primary key. If the index is meant to improve performance, it should include additional fields that are frequently used in queries or filters.
  Remove Redundant Index: If the index is indeed identical to the primary key, consider removing it. The primary key itself serves as an efficient way to access records, and an additional index on the same fields is unnecessary.
  Adjust Modeling: If you need to create an index for performance reasons, adjust the fields included in the index to ensure they provide additional value beyond what the primary key offers.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional context or updates regarding this error message.
  Performance Tuning: When designing indexes, consider the overall performance of your queries and how indexes can be used to optimize data retrieval without redundancy.
  Data Modeling Best Practices: Familiarize yourself with best practices in data modeling within SAP BW, especially regarding the use of primary keys and indexes in ADSOs.
  
  If the issue persists after following these steps, it may be beneficial to consult with an SAP BW expert or reach out to SAP support for further assistance.
