Change run is a procedure used to activate characteristic data changes.

Characteristics are descriptions of key figures, such as Customer ID, Material Number, Sales Representative ID, Unit of Measure, and Transaction Date. The maximum number of characters allowed for the technical name is 9.

A client is a subset of data in an SAP system. Data shared by all clients is called client-independent data, as compared with client-dependent data. When logging on to an SAP system, a user must specify which client to use. Once in the system, the user has access to both client-dependent data and client-independent data.

The communication structure is the structure underlying the InfoSource.

A compound attribute differentiates a characteristic to make the characteristic uniquely identifiable. For example, if the same characteristic data from different source systems mean different things, then we can add the compound attribute 0SOURSYSTEM (source system ID) to the characteristic; 0SOURSYSTEM is provided with the Business Content.
