T+12.0销货单审核时报错：Item has already been added. Key in dictionary: 'fc86ce55-29ff-4ad7-9064-a53200a246f96949d13e-97e3-4f11-aa0e-a4a5011cf37c' Key being added: 'fc86ce55-29ff-4ad7-9064-a53200a246f96949d13e-97e3-4f11-aa0e-a4a5011cf37c'.

在数据库中查询后，发现fc86ce55-29ff-4ad7-9064-a53200a246f9是一个存货在数据库中的id,6949d13e-97e3-4f11-aa0e-a4a5011cf37c是一个仓库的id.

于是将存货id:fc86ce55-29ff-4ad7-9064-a53200a246f9中的几个字符稍做修改。然后再登录系统审核这张销货单，结果审核成功。
