Difference between Master data Activation and Attribute Change Run

• Master Data Activation = Activation
• Attribute Change Run = (Master Data Activation) + Extra features
• Master Data Activation
• When the data is loaded to the InfoObject, it is present in ‘M’ Version, which is modified version. Only after the infoObject is activated, it changes to Active (A) version and is available for reporting.
• Attribute Change Run
• It does the Master data activation, along with the following tasks
• It realigns the Aggregates for the changed attributes. 
• It is also used when Navigational Attributes are used in the Aggregates. Once the request is loaded to cube and Roll up has been done. So after doing Rollup, if the value of the Master Data changes, that will not be reflected in the aggregates. As, when a query is executed, it gets the data from the Aggregates. In our case, the master data value changed after rollup, so the value is different in Aggregate and Cube. So, if we do Attribute Change Run, whenever there is a change in the master data value, it informs the change of master data value.
