ZCL_ODATA_ERROR_HANDLER

This class converts ABAP exceptions into OData-compatible error responses. It should be used in the DPC_EXT constructor to handle framework exceptions.

Usage

The error handler is typically used in the DPC_EXT constructor:

METHOD constructor.
  super->constructor( ).
  TRY.
      mt_data_providers = NEW #( me ).
      NEW zcl_odata_fw_controller( 'Z_MY_PROJECT'
        )->define_dpc( mt_data_providers ).
    CATCH zcx_odata INTO DATA(lo_error).
      NEW zcl_odata_error_handler( me )->raise_exception_object( lo_error ).
  ENDTRY.
ENDMETHOD.

Methods

constructor

Creates a new error handler instance with the DPC context.

raise_exception_object

Converts any ABAP exception (CX_ROOT) into a /IWBEP/CX_MGW_BUSI_EXCEPTION that the OData runtime can handle. The error text from the original exception is preserved and shown in the UI message manager.
