• What is the cause and solution for SAP error message RS_ADSO_MODEL161 - All Char. are Key is set. Field '&1' with type '&2' is not allowed. ?

  The SAP error message RS_ADSO_MODEL161 indicates that there is an issue with the configuration of an Advanced DataStore Object (ADSO) in SAP BW/4HANA or SAP BW on HANA. Specifically, the error states that "All characteristics are key" is set, but a field with a certain type is not allowed in this context.
  Cause:
  This error typically occurs when you have defined all characteristics in your ADSO as key fields, but you are trying to include a field that is not compatible with this setting. In an ADSO, if all characteristics are defined as key fields, then any additional fields that are not key fields (like text fields or non-key attributes) cannot be included.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review ADSO Configuration:
  
  Go to the ADSO definition in the SAP BW modeling tools.
  Check the settings for the characteristics and ensure that you are not trying to include non-key fields when "All characteristics are key" is set.
  
  
  
  Adjust Key Settings:
  
  If you need to include non-key fields, consider changing the setting so that not all characteristics are defined as key fields. You can do this by unchecking the "All characteristics are key" option.
  
  
  
  Modify Field Types:
  
  If you need to keep the "All characteristics are key" setting, ensure that all fields you are trying to include are compatible with being key fields. This means they should be of a type that can be used as a key (e.g., characteristic types).
  
  
  
  Check Field Definitions:
  
  Ensure that the field type of the field mentioned in the error message (e.g., &2) is appropriate for the ADSO configuration. If it is a text field or a non-key attribute, it should not be included if all characteristics are set as key.
  
  
  
  Rebuild the ADSO:
  
  If necessary, you may need to recreate the ADSO or adjust its structure to meet your requirements.
