Attr Change Run Master Data Infoobject PChain

Question

In the master data process chain process type Attribute Change Run which is usually at the end of the chain updates the changes in the master data infoobjects.
The Chain is usually designed with full infopacks and say if it is scheduled every night , isn't it loading the master data again ( duplicating ) and again even though considering the process type Attribute Change Run at the end.
Is it like just the attribute change run is executed for updates ?If thats the case why do we need a process chain for Masterdata...if its only one time full ..that can be done manually right?
Am I missing something here ...?

If you look at the detail in the Monitor for a Master Data load, it will tell you how many recordssent from R/3 and how many records were updated and inserted.
As far as static master data that deos not regularly have new records or changes - you're right you don't need to load those objects daily, they could be loaded perhaps monthly.
You might consider balancing how fancy you try to get with breaking up master data into different groups, loading some daily, and other sweekly, others monthly, etc.  In our case we use to have a fairly elaborate master data load schedule, loading someobjects 1st Tuesday of the month, others 2nd, Tues, others 3rd etc, and then we had weekly loads and dailys.  When I began to review the run times involved, it was apparent that the various monthly loads, in total, ran less than 10 minutes, so I just consolidated the 4 differently monthly maser data loads and the weekly loads all into a single process chain.  While much of the this master data doesn't change much, it was much easier to just schdule mastr data either daily or weekly, rather than getting too elaborate.
Now if run time of master data loads or change runs sarts to become an issue, then you might have to adopt a more elaborate schedule. It really depends on your environment.
