急【库存关账】执行关账失败the merge statement attempted to

点击【库存关账】报错“执行关账失败”，提示信息如下：
The MERGE statement attempted to UPDATE or DELETE the row more than once. This happens when a target row matches more than one source row. A MERGE statement cannot UPDATE/DELETE the same row of the target table multiple times. Refine the ON clause to ensure a target row matches at most one source row, or use the GROUP BY clause to group the source row.

中文意思是：MERGE语句试图多次更新或删除同一行。目标行与多个源行匹配时会出现这种情况。MERGE 语句无法多次更新/删除目标表的同一行。请简化 ON 子句，以确保目标行最多与一个源行匹配，也可以使用 GROUP BY 子句对源行分组。
