今天去官方的apps上看了下，发现Merge Duplicate Products这个模块，不过目前的版本在我的OE里面安装会报错

报错内容如下：

先留个贴在这里，我会关注这个模块的。
-
你在addons 里检查一下, 是否有 product_do_merge 这个模块. 如果没有, 还需要依赖于这个名称的模块的.
-
感谢mrshelly <br / https://www.openerp.com/apps/7.0/product_do_merge/ br />我发现product_do_merge就是Merge Duplicate Products ，就是安装这个模块的时候报错的。。。
-
在这个模块中搜一下“res_group_product_do_merge”字串，可能是没有定义，或写错了xml-id
-
product_do_merge/security/res_groups.xml
第四行 改为
<record id="res_group_product_do_merge" model="res.groups">

谢谢校长，谢谢jeff，今天发奋图强继续研究oe和整理之前的笔记（万恶的evernote 把本来的笔记丢到垃圾桶了，捡回来后发现需要好好整理下）
发现了 jeff和校长的解决方案，明天继续实施 这个模块
-
Merge Duplicate Products
这个模块好像修复了，我又下载了一次，能顺利安装了
在用户 权限 这里 有个 勾，勾选一下，
仓库 这里就出现了 tools duplicate products 这个选项了，
见图
-
这个模块有啥作用？
-
贴段英文介绍：
Merge Products
We can merge duplicates products and set the new id in all documents of product merged.
We can merge products using like mach parameter these fields:
Name
Reference
We can select which product will be the main product.
This feature do not change anything if the products to be merged have operations in different units of measure.
This feature is in the follow path Warehouse/Tools/Duplicate products also is created an action menu in the product view.
不过我测试了下，好像没法合并 重名产品的，我估计产品 如果有 其他单据关联就不能合并，所以 估计也没啥大用。
