The first row that has multiple members, all of the same dimension, is identified as a column dimension. All the dimensions that are placed above this row are candidates for page dimension, if they comply with the rules for page dimension. There is an exception to this rule, as shown in Figure 13, . According to the rules described to this point, you might expect Product and Market to be interpreted as page dimensions. However, Smart View interprets Product and Market as column dimensions, making this grid invalid.
The Smart View logic is that if you identify the first column dimension on row R, and let C be the first column on this row R that contains a member, for each subsequent row above row R, if there is a member on the same column C and that row does not contain any other members, then that row is identified as a column dimension. Each such row that contains a member that is “stacked” on top of column C is a column dimension. A row that does not obey this condition is a candidate for a page dimension as long as it complies with the rules for page dimensions.
