Flag that indicates whether the crosstab data is already sorted according to the row bucket expressions and group bucket expressions (in this order). The crosstab calculation engine can optimize the calculations if the data is sorted by the row groups and column groups. For example, if there are two row groups R1 and R2 (subgroup of R1) and three column groups C1, C2 and C3 the data should be sorted by R1, R2, C1, C2, C3. | ||||||||||
