Selecting the Allow Any check box in a Dimension record lets you enter a blank instead of entering every different domain value for that dimension. This blank is called a null value wildcard. It represents all possible values in the given attribute's domain.
For example, you sell T-shirts that come in the colors white, gray, and red, and also come in the sizes small, medium, large, and extra-large, with the pricing shown in Table 10.
There is no markup for any color except red. The red T-shirts are marked up $2, except for the extra-large size, which is marked up $5. Instead of the long list shown in Table 10, you can represent this with the short list shown in Table 11.
In Table 11, the first row represents all the colors except red, and the second row represents all the sizes of red except extra-large.
If you do create several rules that represent the same combination of condition dimensions, the application uses the rule with the most exact matches (not blanks) in the condition dimensions as the highest priority for processing. Priority is specified using the Sort Order field of the dimension.
