Shortcuts are less flexible from a presentation perspective than model objects, but they require much less maintenance because they are automatically updated when the target object is updated. If maintenance is a key concern and there is no need to customize the appearance of the query subject, use shortcuts.

Framework Manager has two types of shortcuts:

regular shortcuts, which are a simple reference to the target object.

alias shortcuts, which behave as if they were a copy of the original object with completely independent behavior. Alias shortcuts are available only for query subjects and dimensions.

Regular shortcuts are typically used as conformed dimensions with star schema groups, creating multiple references with the exact same name and appearance in multiple places. In the example below, the shortcuts created for Products and Order Time behave as references. If a query is written that brings Products from both Product Forecast and Sales Target, the query uses the definition of Products based on the original and this definition appears only once in the query.


Alias shortcuts are typically used in role-playing dimensions or shared tables. Because there is already an example in this document for role-playing dimensions, we will look at the case of shared tables. In this example, Sales Staff and Sales Branch can be treated as different hierarchies. From our knowledge of the data, we know that because staff can move between branches, we need to be able to report orders against Sales Branch and Sales Staff independently as well as together. To achieve this, we need to create an alias to Sales Branch that can be used as a level in the Sales Staff hierarchy.


With the new alias shortcut in place, it is possible to create queries that require orders by sales branch and orders by sales staff with their current branch information simultaneously.

提供思路，我们在创建一个cube的时候，我们要对cube进行分组，若每月一张，我就把时间维度中的月当作一个分组的依据。之后一个月会生成一个小cube。
但是如果每月新增数量过大，且客户想把很多个月方在一张报表中，那除了等待比较长的cube生成和更新时间，我目前还没有想到什么好办法.

不知道你想干啥，但是想说你描述的，可以。

这错误还真没有见到过，BmtActionsHelper.cpp(500) 没有见到过。
但是 有人 遇到过，说是 ：
Cause:运行FM的操作系统用户对cognos目录树没有足够的权限
Resolving the problem: 针对cognos文件夹目录，给予系统用户足够的操作权限或者Administrator一样。

再不行，重启下 服务器，在删除试试。

过滤器有简单的用过，感觉和sql的where条件差不多~那字段取设置条件 不符合的数据会被过滤
