SAP Message RSRCACHE021 - BLOB table for large data

Diagnosis
If this option is selected, cache entries with query data that exceedthe predefined size limit when initially created are written to the BLOBtable (table with XSTRING). It is preferential to use BLOB tables whentransporting larger data volumes between the database and applicationserver. However, it is not possible to save in internal tables; thismeans that the data export cannot take place in an internal tableinstead of an XSTRING, which would actually offer better performanceunder some circumstances.
