Summary : 
      When an ABAP program accesses a cluster table exceeding the R/3 kernel-determined memory limit of approximately 7.8 MB, it terminates with a short dump error, DBIF_RSQL_NO_MEMORY. This happens due to insufficient memory allocation triggered by the exceeded limit. SAP Note advises deactivating this size restriction by setting "rsdb/rclu/cachelimit=0" in instance profiles (excluding DEFAULT.PFL) and restarting the R/3 system. This change is necessary across all relevant R/3 systems for consistent data management. Additionally, for environments like AS/400 and NT, specific instructions are provided to set the corresponding environment variables. As of Release 4.6A, the size restriction will be lifted.
