  • Message number: 630

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

  • Show details Hide details
  • 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.
