• What is the cause and solution for SAP error message RS_DB_DB6523 - Too many MDC indexes defined for table &1 ?

  The SAP error message RS_DB_DB6523 indicates that there are too many Multi-Dimensional Cube (MDC) indexes defined for a specific table in the SAP BW (Business Warehouse) system. This error typically arises when the number of MDC indexes exceeds the limit set by the database or the SAP BW system configuration.
  
  Cause:
