Parent DIF

Definition

This field allows an association between generalized aggregated DIFs (parents) and DIFs with highly specific information (children). Population of the Parent_DIF field should be reserved for instances where a multitude of DIFs are basically subsets that can be better represented by one parent DIF that describes the entire collection. Typically, the parent DIF will have many children DIFs, all of whom point to the parent. In some instances, a child may point to more than one parent.
