  The SAP error message RSO_RES_ADSO171 indicates that a key field has been added to an Advanced DataStore Object (ADSO) in SAP BW/4HANA or SAP BW on HANA. This error typically arises when there is a mismatch between the data model in the ADSO and the data source or when the data source is not aligned with the current structure of the ADSO.
