在 SQL Server 2012 Data Quality Services 中，我需要清理 Term Based Relation 中的数据，如下所示：

字符串替换**

沃尔玛**

沃尔玛沃尔玛**

沃尔玛**

沃尔玛

即“wal”、“wlr”和“wlt”必须替换为“walmart”，最后“walmart”替换为空白。

它显示错误为

Message Id: DataValueServiceTermBasedRelationCorrectedValueAlreadyCorrectingValue
Term Based Relation (walmart, ) cannot be added for domain 'keywordphrase' because 'walmart' value already exists as a correcting value.

对解决方案的任何建议谢谢，

据我了解，DQS 不支持多级替换（即 a->b 然后 b->c）。为什么不直接在前三个学期做空呢？
