相关屏蔽

相关屏蔽

相关屏蔽会将源数据的多个列置换为相同字典行中的数据。
数据屏蔽转换对多个列执行置换屏蔽时，屏蔽的数据可能包含不切实际的字段组合。可以配置相关屏蔽，以便置换同一字典行中多个输入列的数据。屏蔽的数据将接收到有效组合，例如“New York, New York”或“Chicago, Illinois”。
配置相关屏蔽时，请先配置进行置换屏蔽的输入列。配置要与该置换列相关的其他输入列。例如，选择邮政编码列进行置换屏蔽，然后选择要与该邮政编码列相关的城市列和省/自治区/直辖市列。相关屏蔽可确保所置换的城市和省/自治区/直辖市值对于所置换的邮政编码值有效。
如果没有先配置进行置换屏蔽的列，将无法配置相关屏蔽列。
配置相关屏蔽列时，请配置以下屏蔽规则：
相关列
要配置为置换屏蔽的输入列的名称。数据屏蔽转换将使用适用于该列的屏蔽规则从字典中检索置换数据。配置为置换屏蔽的列将成为从字典中检索屏蔽数据的键列。
输出列
字典列的名称，其中包含配置为相关屏蔽的列的值。
