Things to Avoid When Creating Business Logic Formulas

When creating Business Logic formulas, be sure to bear in mind the following:

• Never assign a null value to a global variable. Assigning a null value may cause the PSLWriter to fail when calculating the Metric. If an uninitialized value is needed, use Empty instead.
• Avoid using map and vector objects in Clustered Metrics. If these objects must be used, keep them as small as possible. Clustered Metrics containing big maps and vectors take a long time to calculate.
