How To Fix RSD_TREX512 - Check definition of logical index (&1 &2)

SAP Error Message - Details

• Message type: E = Error

• Message class: RSD_TREX - Messages from TREX Aggregate Area

• Message number: 512

• Message text: Check definition of logical index (&1 &2)

Description
In this test, the system compares the definitions of each of the indexes
for a BWA index with the current versions of the database tables. The
system checks whether the number, name, and type of the table fields in
the database match the definition for the index on the BW accelerator
server.
An index can have changed if, for example, the InfoCube was changed. If
this is the case, the BWA index has to be repaired (see test "BWA Index
Adjustments After InfoCube Activation").
Note that if you do <ZH>not</> specify an InfoCube, the system executes
the test for all InfoCubes that have a BWA index.
Repair
If an index has changed, the old index is deleted and the new index is
created with the correct definition and filled. Note that this process
can take some time, depending on the size of the table. All BWA indexes
that use this index are set to "inactive" and are not available for
reporting during this time.
