InfoObject加载后的Change Run

When master data changes of the nav. attribute or

hierarchies must be applied to the depending aggregates .

this process is called change run or attribute change run.

Newly loaded master data is not active until the change run

applied the changes to all aggregates

 

change run的用处

1、  激活属性有效性

2、  激活cube 聚集中由于navigation attribute生成的DIMENSION表，由于聚集中的维度是根据最初的信息对象中导航属性关系生成的DIMENSION表，所以当主数据和属性的关系更改时候，需要重新生成聚集和维度（特指由导航属性生成的维度）的关系；
