You can restrict access to master records in order to prevent unauthorized changes. Depending on how you organize your master data, you can assign authorizations for maintaining this data. For example, one user may have authorization to maintain all master data, while another may have authorization to maintain only accounting master data.
You can even assign authorizations for different types of processing. All users could have authorization to display master records while only a limited group of users may be able to create and change master data.
Authorizations are specified during system configuration and assigned to each user in her user master record. The Implementation Guide for Financial Accounting explains how to set up authorizations. For more information on configuring the system, seeConfiguring the System Using the Implementation Guide.
