Error description

  • When applying Zero Suppression on large (PowerCube) reports, the
    performance is significantly slower in the C10 studios than it
    is in PowerPlay.  In this case, the customer has an analysis
    with 7 levels of nesting on rows and 8 measures (several of them
    calculated) on columns.  The default Zero Suppression operation
    on this large report can take several minutes in ANS and RS,
    while a similar report in PowerPlay Studio takes less than 20
    seconds to suppress.  While a configurable fix was put into the
    code in 2012 to address a similar performance issue (Request
    COGCQ00678459), it does not cover all zero suppression options
    and is therefore of little use, as is, in this case.  The
    purpose of this request is to provide customers with a means of
    significantly improving the performance of complete zero
    suppression in the Cognos 10 Studios, so that it closer to what
    they saw in PowerPlay.
