• What is the cause and solution for SAP error message RSO_RES_ADSO173 - No source characteristic for time derivation ?

  The SAP error message RSO_RES_ADSO173 indicates that there is an issue with the time derivation in the context of an Advanced DataStore Object (ADSO) in SAP BW/4HANA or SAP BW on HANA. This error typically arises when the system cannot find a source characteristic that is required for the time derivation process.
  Cause:
  The error can occur due to several reasons:
  
  Missing Time Characteristic: The time characteristic (e.g., calendar year, month, day) that is needed for the time derivation is not defined in the ADSO or is not mapped correctly.
  Incorrect Data Model: The data model may not be set up correctly, leading to missing relationships or mappings between the source and target characteristics.
  Transformation Issues: There may be issues in the transformation rules that are supposed to derive the time characteristic from the source data.
  Data Source Configuration: The data source from which the ADSO is pulling data may not have the necessary time characteristics defined.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check the ADSO Definition:
  
  Go to the ADSO definition in the SAP BW modeling tools.
  Ensure that the time characteristic is included in the ADSO structure.
  
  
  
  Review the Transformation:
  
  Check the transformation rules that are used to load data into the ADSO.
  Ensure that the time characteristic is being derived correctly from the source data.
  
  
  
  Validate Data Source:
  
  Verify that the data source being used has the necessary time characteristics defined.
  If the data source is an InfoProvider or another ADSO, ensure that it contains the required time fields.
  
  
  
  Check for Missing Mappings:
  
  In the transformation, ensure that there are no missing mappings for the time characteristic.
  If necessary, add the required mappings to derive the time characteristic.
  
  
  
  Test the Data Load:
  
  After making the necessary adjustments, test the data load to see if the error persists.
  Monitor the process for any additional error messages that may provide further insight.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific version of SAP BW/4HANA you are using for any known issues or additional troubleshooting steps.
