SAP Error Message - Details

• Message type: E = Error

• Message class: RSD_TREX - Messages from TREX Aggregate Area

• Message number: 542

• Message text: Delete BWA index data from main memory ('&1')

Description
Using this test, you can delete all data for a BWA index from the main
memory.
Master data indexes that are still required by other InfoCubes are <ZH>
not</> deleted from the main memory. The data on the file server is <ZH>
not</> deleted; this means the BWA index is still active.
This action is useful if storage in the main memory is low and the main
memory contains data that is rarely or no longer used, or data for which
the performance of the initial execution of a query (and the
corresponding read from the file server in the main memory) is
insignificant.
Note that if you do not specify an InfoCube, the system executes the
selected action for all BWA indexes that are active and filled.
Repair
This test has no repair.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
