• What is the cause and solution for SAP error message RS_ADSO_MODEL058 - All Characteristics are Key is set; "Unique data records" not allowed ?

  The SAP error message RS_ADSO_MODEL058 indicates that all characteristics in an Advanced DataStore Object (ADSO) are set as key fields, which leads to a conflict with the setting of "Unique data records." This error typically arises when you are trying to load data into an ADSO that has been configured in a way that does not allow for the uniqueness of records.
  Cause:
  
  All Characteristics as Key Fields: The ADSO is configured such that every characteristic is defined as a key field. In this case, the system expects that each combination of key fields will be unique, which contradicts the "Unique data records" setting.
  Data Loading Configuration: The data loading process may be attempting to insert records that are not unique based on the defined key fields.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Review Key Field Configuration:
  
  Check the configuration of the ADSO in the Data Warehousing Workbench (transaction RSA1).
  Determine if all characteristics need to be key fields. If not, modify the ADSO definition to remove the unnecessary key field designation from some characteristics.
  
  
  
  Adjust "Unique Data Records" Setting:
  
  If it is acceptable for the ADSO to allow non-unique records, you can change the setting for "Unique data records" to allow duplicates. This can be done in the ADSO settings.
  
  
  
  Data Quality Check:
  
  Ensure that the data being loaded does not contain duplicates for the key fields defined in the ADSO. If duplicates exist, you may need to cleanse the data before loading.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to ADSO configuration and data loading to ensure compliance with best practices.
  
  
  
  Related Information:
  
  ADSO Configuration: Understanding how to configure key fields and data loading settings in ADSOs is crucial. Familiarize yourself with the Data Warehousing Workbench and the specific settings for your ADSO.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates related to this error message.
  Data Modeling Best Practices: Familiarize yourself with best practices for data modeling in SAP BW/4HANA or SAP BW on HANA, as this can help prevent similar issues in the future.
  
  By following these steps, you should be able to resolve the RS_ADSO_MODEL058 error and successfully load your data into the ADSO.
