• What is the cause and solution for SAP error message RSO_RES_ADSO203 - Characteristic &1 has been added to key because of compounding with &2 ?

  The SAP error message RSO_RES_ADSO203 indicates that a characteristic has been added to the key of an Advanced DataStore Object (ADSO) due to compounding with another characteristic. This typically occurs in the context of data modeling in SAP BW/4HANA or SAP BW on HANA, where characteristics can be compounded to create a more granular key for data storage and retrieval.
  Cause:
  The error arises when:
  
  You are trying to activate or process an ADSO that has characteristics defined in a way that requires compounding.
  The system automatically adds a characteristic to the key because it is compounded with another characteristic, which may not be expected or desired in your data model.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Review the Data Model:
  
  Check the characteristics defined in your ADSO. Look for any compounding relationships that may not be necessary or that you did not intend to create.
  Ensure that the characteristics are correctly defined and that their relationships are as expected.
  
  
  
  Adjust Compounding Settings:
  
  If compounding is not required, you can modify the settings of the characteristics in the InfoObject definition. You can remove the compounding relationship if it is not needed for your reporting or data processing needs.
  
  
  
  Re-activate the ADSO:
  
  After making the necessary adjustments, try to re-activate the ADSO. This should resolve the error if the compounding relationships are correctly configured.
  
  
  
  Check for Dependencies:
  
  Ensure that there are no other dependencies or settings in your data model that might be causing the characteristic to be added to the key unexpectedly.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed information on compounding characteristics and how they affect ADSO keys.
  
  
  
  Seek Support:
  
  If the issue persists, consider reaching out to SAP support or consulting with a BW/4HANA expert who can provide more tailored assistance based on your specific data model and requirements.
