This is usually a keylinks problem. IBO is trying to specify a single
record using its key value, but IB is responding with multiple rows.

Note that you must specify KeyLinks in full in the detail dataset AS
WELL AS the masterlinks required for the master-detail relationship.
Often one (or more) of the fields is common to both properties but
because that is not always the case, you must specify the keylinks so
that they will uniquely identify a record regardless of the
masterlinks settings.
