Parameter passing allows you to define a relationship between two fields that are not
directly connected by a relationship, but instead are linked together through a series of records
that have relationships defined between them.
In a typical relationship between records in a Business Record diagram, a relationship is defined
between a master record and its child record, and the parameter passed is defined (typically) by the
primary/foreign key relationship between the two records.
Advanced parameter passing takes this further, allowing you to specify parameters that will pass
through one or more records in a relationship chain. Figure: Advanced parameter passing
In order for the passing to work, the following must be true:
You must have specified the proper fetch order of the records. The record containing the primary
key must be fetched prior to the record containing the foreign key. This is set up by specifying the
fetch order.
You must have specified proper settings for the occurrences property. Advanced parameter passing
will only work if the occurrences property is set to either 1-0 or 1-1 on the relationships between
the involved records. Failure to meet this criteria will result in a pair of error messages: the
first where the error occurs, the second locating the source of the error.
