DSM

An SAP Data Source Model (DSM) is complex because it is designed to account for all the permutations and combinations that exist within a real-life business process. However, such an interface is not suitable for the vast majority of users.

A Public Solution Model (PSM) on the other hand, provides a simplified interface to the SAP Data Source Model.

It is created by adapting the DSM leaving only those fields needed for the simplified business scenario.
