Functionality
The function module RPY_ENTITY_READ reads information for ONE entitytype of the Data Modeler and supplies them in the form of structuresand tables.
The transport object (entity type) and further infromation in theenvironment of the transport object are read.
INCLUDE RPY_UENO_TRANSPORT_OBJECT OBJECT DOKU ID TX
INCLUDE RPY_UENO_WITH OBJECT DOKU ID TX
INCLUDE RPY_DM_ERRORS OBJECT DOKU ID TX

Example
With the following example you select all relevant information aboutone entity type, in this case materials.Precisely the transport object is selected.
