  • Closed as program error.

Error description

  • EQQCPHVA fails a check which is designed to prevent navigation
    on successors which do not belong to a just added occurence,
    while the EQQCPHVA task is still processing the add occurence.
    This can lead to very heavy extra, but unnecessary navigation;
    and possibly a loop could occur because the checked fields are
    not yet correctly initialized.
