What does the /*+ SHORT_SUM_VALUES */ hint mean in BW queries?
This hint is not relevant for the strategy and therefore does not have any effect on the query processing sequence. This hint ensures that, when the totals are being formed using the columns, the actual length of a numeric field is used for the calculation rather than the maximum field length. For more information, see Note 723020. In relation to the hints, see also Notes 652096 and 832544.
