Purchasing Information System (MM-IS-PU)
A purchasing information system gives an overview of data and processes in purchasing.
This scenario makes this overview possible in distributed purchasing systems also (For example: A central view of release orders on contracts).
Logistics data is sent from the decentral purchasing systems to the central purchasing information system, where it causes information structures to be updated.
Restrictions
In the central purchasing information system any of the information structures can be updated according to any sets of rules. Therefore the decentral purchasing systems have to supply all the logistics data that is available for each action.
Data is always sent for individual documents.
One consequence of this is that there is a very large volume of data traffic, and therefore a significant load on the network.
