How To Fix RSD_TREX630 - Verification of buffer entries in BWA hierarchy buffer

SAP Error Message - Details

• Message type: E = Error

• Message class: RSD_TREX - Messages from TREX Aggregate Area

• Message number: 630

• Message text: Verification of buffer entries in BWA hierarchy buffer

Description
When queries in hierarchies are executed, the relevant hierarchy nodes
are expanded to the relevant leaves. This leaf-node relation is saved in
a temporary index in the BI accelerator. The hierarchy buffer manages
expanded hierarchies according to an LRU (least recently used)
algorithm.
The check verifies whether all temporary indexes in the hierarchy buffer
contain the correct data.
Repair
If the hierarchy buffer contains incorrect entries, write a customer
message. This is an erroneous state.
If you urgently need to resolve the error, you can delete the entire
hierarchy buffer. Note that once you do this, a customer message is
superfluous as it is no longer possible to trace the error.

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