Implementation of a Read Operation Description

GET_CONVERTED_KEYS returns a structure that has the same type as the entity but only the key fields are filled, so there is no need to loop over a list of key fields.

The selected data must be returned using the export parameter ER_ENTITY. The object IO_TECH_REQUEST_CONTEXT is used to retrieve data from the HTTP request. ER_ENTITY is based on a type ZCL_Z_GW100_000_MPC=>TS_PRODUCT defined in the model provider class.

Errors should be raised by using the exceptions /IWBEP/CX_MGW_BUSI_EXCEPTION for errors in the business logic, while technical exceptions should be raised by using /IWBEP/CX_MGW_TECH_EXCEPTION.
