ABAP Dictionary Type to EDM.Type Mapping SP10Locate this document in the navigation structure

Use

For properties that are automatically added for each field of the so-called auto-expand include (simple field extensibility) there is a special EDM type determination logic in method /IWBEP/CL_MGW_MED_EDM_UTIL->GET_EDM_TYPE_V2.

You can also use this EDM type determination for all non simple field extensibility properties instead of the default EDM determination by using method /IWBEP/CL_MGW_ODATA_MODEL->/IWBEP/IF_MGW_ODATA_MODEL~SET_MODEL_FEATURES and setting the model feature use_edm_mapping_sp10.

The following table shows how the metadata base class /IWBEP/CL_MGW_ABS_MODEL maps ABAP Dictionary types in case this mapping is used.
