3.11.3.2 Managing Large Cross Product Static Table Drivers

To build a Static Table Driver that will have a very large cross product, follow the normal steps of building out your Key leaf (or node) values and your Target leaf values on the Static Table Driver Definition tab. If you start with a modest number of defined Key and Target leaves, the Coefficients tab operates normally, and you may save coefficients for any possible combination of Key and Target leaves that you have defined on the Definition tab.

If you navigate to the Definition tab, add more Key leaves and Target leaves, and then return to the Coefficients tab, the Coefficients tab allows you to edit coefficients for any possible combination of your selected Key and Target leaves. This is applicable as long as you have not exceeded the cross-product limit. After you have added enough combinations on the Definition tab for the rule to exceed to cross-product limit, the Coefficients tab no longer shows the unmapped combinations. In this state, you can edit the coefficient values for any previously mapped combination, but you can no longer establish new combinations and coefficient values within the Coefficients tab.

Note:

Instead of starting the build process with a modest number of Key leaves and Target leaves, you might also begin by specifying a very large number of Key and Target leaf values. If you specify enough values in the Definition tab to exceed the cross product limit, then when you initially transition to the Coefficients tab it will appear blank.

Regardless of whether your Static Table Driver rule begins as a small rule and evolves into a large cross product rule or your Static Table Driver rule was "large" at the time it was defined, the Coefficients tab only displays the "defined" combinations after you have exceeded the cross- product limit.
