• What is the cause and solution for SAP error message RS_ADSO_MODEL070 - All Characteristics are Key is set. Def. of hash partition not allowed. ?

  The SAP error message RS_ADSO_MODEL070 indicates that all characteristics in an Advanced DataStore Object (ADSO) are set as key fields, which prevents the definition of hash partitions. This error typically arises when you are trying to create or modify an ADSO and the configuration does not allow for hash partitioning due to the key settings.
  Cause:
  
  All Characteristics as Key Fields: The primary cause of this error is that all the characteristics in the ADSO are defined as key fields. In SAP BW/4HANA, hash partitioning is not allowed when all characteristics are keys because hash partitioning requires at least one non-key field to distribute the data across partitions effectively.
  
  Solution:
  To resolve this error, you need to modify the key settings of your ADSO. Here are the steps you can take:
  
  
  Review Key Fields: Open the ADSO in the Data Warehousing Workbench (transaction code RSA1) and review the characteristics that are defined as key fields.
  
  
  Change Key Settings:
  
  Identify if any of the key fields can be changed to non-key fields. This typically involves business logic considerations, as you need to ensure that the data model still meets your reporting and analytical needs.
  If possible, remove one or more characteristics from the key definition to allow for hash partitioning.
  
  
  
  Reconfigure the ADSO: After making the necessary changes to the key fields, save and activate the ADSO again.
  
  
  Test the Configuration: After reconfiguration, test the ADSO to ensure that it works as expected without triggering the error.
  
  
  Related Information:
  
  Hash Partitioning: This is a method of distributing data across multiple partitions based on a hash function. It is useful for performance optimization in large datasets.
  Key Fields in ADSO: Key fields are used to uniquely identify records in the ADSO. They are critical for data integrity and reporting.
  SAP Documentation: For more detailed information, refer to the official SAP Help Portal or the SAP Community for best practices and guidelines on configuring ADSOs.
  
  By following these steps, you should be able to resolve the RS_ADSO_MODEL070 error and successfully configure your ADSO for optimal performance.
