• What is the cause and solution for SAP error message RS_DB_DB2123 - Incremental update of table &1 on accelerator &2 not allowed ?

  The SAP error message RS_DB_DB2123 indicates that an incremental update of a specific table on a database accelerator (like SAP HANA) is not allowed. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when trying to perform an incremental data load to a data target that does not support it.
  Cause:
  
  Table Configuration: The target table may not be configured to allow incremental updates. This can happen if the table is set up in a way that only allows full loads or if it is a non-accelerated table.
  Data Source Settings: The data source from which the data is being pulled may not support incremental updates.
  Data Model: The data model may not be designed to handle incremental updates for the specific table in question.
  Technical Settings: The technical settings of the InfoObject or InfoProvider may restrict incremental updates.
  
  Solution:
  
  Check Table Configuration: Verify the configuration of the target table in the data warehouse. Ensure that it is set up to allow incremental updates.
  Review Data Source: Check the settings of the data source to ensure it supports incremental updates. If it does not, consider changing the data source or modifying the extraction logic.
  Adjust Data Model: If the data model is not designed for incremental updates, you may need to redesign it or use a different approach for data loading.
  Technical Settings: Review the technical settings of the InfoObject or InfoProvider. Ensure that the settings allow for incremental updates.
  Use Full Load: If incremental updates are not feasible, consider performing a full load instead of an incremental load.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP BW or SAP HANA you are using for any additional guidance or updates.
