FieldClass FlowField

FlowFields must be dynamically calculated. FlowFields are virtual fields that are stored as metadata; they do not contain data in the conventional sense. FlowField contains the definition of how to calculate (at runtime) the data that the field represents and a place to store the result of that calculation. Generally, the Editable property for FlowField is set to No.

Depending on the CalcFormula method, this could be a value, a reference lookup, or a Boolean value. When the CalcFormula method is Sum, FieldClass connects a data field to a previously defined SumIndexField in the table defined in CalcFormula. FlowField processing speed will be significantly affected by the key configuration of the table being processed. While we must be careful not to define extra keys, having the right keys defined will have a major effect on system performance, and thus on user satisfaction.

A FlowField value is always 0, blank, or false, unless it has been calculated. If...
