CreateIndirectFieldsPair(crossField, dataField)
Returns an object, which is a descriptor of correspondence between fields for indirect link. The crossField argument specifies a field of cross table in GDB. The field crossField must belong to a GDB table returned by the property DataLink::CrossTable. The dataField argument specifies a field from a table or query of external database. The field dataField must belong to an external database table or query upon which the link descriptor has been built. The crossField and dataField fields must be matched by type. Use the table "Types of Fields" to match the fields by type correctly. To use the fields defined by the created correspondence descriptor in the indirect link, this descriptor should be added to the DataLink::IndirectFieldsPair collection.
