  The SAP error message RSDD_TIP_LOGI123 indicates that there is an issue with the loading behavior of facts in a data model, specifically that no key is defined for the data being loaded. This error typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when working with InfoProviders, such as InfoCubes or DataStore Objects (DSOs).
  Cause:
  The error arises when:
  
  Key Definition Missing: The InfoProvider is set to use key-based loading behavior, but the key fields required for the data load are not defined or are missing in the data source.
  Data Source Configuration: The data source from which you are trying to load data does not have the necessary key fields mapped correctly to the target InfoProvider.
  Transformation Issues: There may be issues in the transformation rules that prevent the correct mapping of key fields from the source to the target.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Key Fields:
  
  Go to the InfoProvider definition in the SAP BW system.
  Ensure that the key fields are correctly defined in the InfoProvider. This includes checking the characteristics that are marked as key fields.
  
  
  
  Review Data Source:
  
  Verify the data source from which you are loading data. Ensure that it contains the necessary key fields that match the InfoProvider's key definition.
  If the data source is an ODS or InfoCube, check the underlying tables to confirm that the key fields are present.
  
  
  
  Transformation Rules:
  
  Check the transformation rules between the data source and the target InfoProvider. Ensure that the key fields from the source are correctly mapped to the key fields in the target.
  If necessary, adjust the transformation to include the required key fields.
  
  
  
  Data Load Process:
  
  If you are using a process chain, ensure that all steps are correctly configured and that the data load process is executed in the correct sequence.
  
  
  
  Test the Data Load:
  
  After making the necessary adjustments, perform a test data load to see if the error persists.
