property MasterFields: string ;
Description
MasterFields together with MasterSource is used to establish a detail-master relationship between this table and table specified in MasterSource.
When MasterSource is set, use MasterFields to define fields which tie this table and master table. Fields are specified as a string containing semicolon-separated list of field names. Fields specified on the list should exist in both this and master table.
If the relation is set, when current record in the master table changes, the new values of the specified fields are used to find corresponding records in this (detail) table.
