what is updating group,info structure,and update check  why we use it

Answer 1

Hi,
Update group for statistics update:--
The update group is a control element in the updating definition, which allows all the different business events in the various applications to have a uniform influence on the statistics update in the Logistics Information System (LIS).
In an application, one update group is allocated to a specific business event or a group of business events. This update group is then used to determine the fields which will be created for the statistics.
The type of allocation and the organizational elements that determine how the allocation takes place vary from application to application.
Information Structures:-
In an information system, data aggregation is necessary in order to ensure that the user has a clear overview of key interrelationships. Since the requirements which need to be satisfied by data aggregation are determined by many different user groups, it is absolutely vital that aggregation functionality is flexible. Experience shows that various user groups need to view aggregated data from many different perspectives.
The SAP system makes these different views possible by providing self-defined information structures.
In the information structures, you can define your own view, by selecting the information from the operative application that you consider worthy of aggregation.
A distinction is made between three types of information:
Characteristics
You can define a maximum of nine characteristics for each information structure. These characteristics form the table keys of the database table.
Key figures
The key figures refer to values with significance to business, which are aggregated by means of the characteristics (e.g. invoiced sales, quantity of incoming orders, order quantity, lead time).
Period split
The periodic cumulation of data is a further criterion for aggregation. The key figures are thus aggregated on a daily, weekly or monthly basis, or on the basis of a variable period split that is determined by the fiscal year variant.
Update Check:--
You can use the update log to monitor the updating of statistical data. The information displayed in the update log is user-dependent and operation-dependent.
The update log is a tool that you can use to check updating once it has taken place, and to check the generation of the information structures and the update rules assigned to them.
You can also use the update simulation function to monitor the update procedure. In addition, you can use update simulation to generate an update log for documents that have not caused an update.
