Data-relation object handle

A handle to a data-relation object. A data-relation object defines one relation between a pair of parent and child buffers in a ProDataSet object that have a one-to-one or one-to-many parent-child relationship. A data-relation object identifies the parent and child buffers, and the fields in each buffer that define the primary and foreign key fields of the relation.

A data-relation object can be static or dynamic. A static data-relation object is one you define at compile time as part of the DEFINE DATASET statement using the data-relation option. A dynamic data-relation object is one you create at run time for a dynamic ProDataSet object using the ADD-PARENT-ID-RELATION( ) method. Use this handle to access the data-relation object's attributes.

Note: Does not apply to SpeedScript programming.
