Summary : 
      For SAP NetWeaver BW Accelerator (BWA) remote configuration or verification checks, specific prerequisites are required. Pre-installation of BWA and an R/3 support connection are essential. Users must have authorization for transactions like RSDDBIAMON2, TREXADMIN, and others. The ST-A/PI and basis SP level prerequisites, along with a TREX/BIA service connection, must be met. Special requirements differ for configuration and verification sessions. Configuration checks require prior use of BWA, whereas verification checks need established usage with a specific statistic level setting. Compliance with these specifications ensures an effective session delivery.
