• What is the cause and solution for SAP error message RS_ADSO_MODEL015 - All Characteristics are Key is set. No further key definition allowed. ?

  The SAP error message RS_ADSO_MODEL015 indicates that all characteristics in the Advanced DataStore Object (ADSO) model have been defined as key fields. This means that the system does not allow any further key definitions because the ADSO is already configured to treat all characteristics as keys.
  Cause:
  The error occurs when you attempt to add or modify a characteristic in the ADSO that would also be defined as a key field, but the ADSO is already set up such that all characteristics are designated as key fields. In an ADSO, key fields are used to uniquely identify records, and having all characteristics as keys can lead to issues with data storage and retrieval.
  Solution:
  To resolve this error, you need to modify the ADSO model to ensure that not all characteristics are defined as key fields. Here are the steps you can take:
  
  
  Review the ADSO Configuration:
  
  Go to the ADSO definition in the SAP BW modeling tools.
  Check the list of characteristics and their key definitions.
  
  
  
  Modify Key Fields:
  
  Identify which characteristics do not need to be key fields.
  Change the definition of those characteristics from key to non-key. This can usually be done in the ADSO modeling screen by deselecting the key option for the relevant characteristics.
  
  
  
  Save and Activate:
  
  After making the necessary changes, save the ADSO definition.
  Activate the ADSO to apply the changes.
  
  
  
  Test the Changes:
  
  After activation, test the ADSO to ensure that it functions correctly and that the error message no longer appears.
  
  
  
  Related Information:
  
  Key Fields in ADSO: Key fields are essential for uniquely identifying records in the data model. It is important to carefully consider which fields should be key fields based on the business requirements.
  Data Modeling Best Practices: When designing data models in SAP BW, it is advisable to limit the number of key fields to avoid performance issues and complexity in data retrieval.
  SAP Documentation: For more detailed information, refer to the official SAP documentation on Advanced DataStore Objects and data modeling best practices.
