Batch Input
Batch input is one of the primary ways in which data can be transferred into an SAP system. Batch input is used primarily for bulk data transfers, for example, the one-time import of data from a legacy system into a newly installed SAP system. Another typical use is for periodic (hourly, daily...) transfers of data from external systems or legacy systems that are still in use into the SAP system, where all enterprise data is consolidated.
Due to the fact that batch input imports data from an external system into the SAP system, you should take the appropriate precautions to protect your system from unauthorized changes. More about batch input and the security measures to take are described in the following topics:
