• What is the cause and solution for SAP error message RS_ADSO_MODEL108 - '&1': Illegal object type '&2' for 'Characteristic as key figure' ?

  The SAP error message RS_ADSO_MODEL108 typically occurs in the context of SAP BW (Business Warehouse) when working with Advanced DataStore Objects (ADSO). This error indicates that there is an illegal object type being used for a characteristic that is defined as a key figure in the ADSO model.
  Cause:
  The error arises when you attempt to define a characteristic as a key figure, which is not allowed. In SAP BW, key figures are typically numeric values (like sales amounts, quantities, etc.), while characteristics are used to describe the data (like product IDs, customer names, etc.). If you mistakenly try to assign a characteristic (which is not a numeric value) as a key figure, the system will throw this error.
  Solution:
  To resolve this error, you should:
  
  
  Check the ADSO Definition: Go to the ADSO definition in the SAP BW modeling tools (like Eclipse or the SAP GUI) and review the characteristics and key figures defined in your model.
  
  
  Correct the Object Type:
  
  Ensure that only numeric fields are defined as key figures.
  If you have mistakenly defined a characteristic as a key figure, change its type back to a characteristic.
  
  
  
  Revalidate the Model: After making the necessary changes, revalidate the ADSO model to ensure that there are no further issues.
  
  
  Transport Changes: If you are working in a development environment, ensure that you transport the changes to the appropriate environments (like QA or Production) after testing.
  
  
  Related Information:
  
  Key Figures: In SAP BW, key figures are typically used for quantitative data and can be aggregated (e.g., sum, average).
  Characteristics: Characteristics are descriptive attributes that provide context to the key figures (e.g., time, location, product).
  Modeling Tools: Familiarize yourself with the SAP BW modeling tools, as they provide functionalities to define and manage ADSOs effectively.
  Documentation: Refer to SAP Help documentation for more details on ADSO modeling and best practices.
  
  By following these steps, you should be able to resolve the RS_ADSO_MODEL108 error and ensure that your ADSO is correctly defined.
