禁用一个用户时，需要判断下该用户是否有被字段更新引用，有的话不允许禁用

[yinlianghui]

即判断有没有字段更新要修改某个对象的选人控件字段（比如ookup/master-detail指向space_users表的字段）值并设置为当前要禁用的用户。

该问题没那么重要，不急处理！

sf文档:Field Update Action Limitations

If a field update references a specific user, you can't deactivate that user. For example, if your field update is designed to change the owner of a record to Bob Smith, change the field update before deactivating Bob Smith.
