error message not shown in response header for OData get_entityset

[soumya_r]

Hi ,

I have created a z odata project with GET_ENTITYSET method redefined and raising an error exception if any error or no data like below but the error is shown in reponse but not in the HTTP header in sap-message although it gives HTTP 500 error.

CALL METHOD me->/iwbep/if_mgw_conv_srv_runtime~get_message_container
      RECEIVING
        ro_message_container = lo_message_container.

    CALL METHOD lo_message_container->add_message
      EXPORTING
        iv_msg_type               = /iwbep/cl_cos_logger=>error
        iv_msg_id                 = 'ZMSG'
        iv_msg_number             = '000'
        iv_add_to_response_header = abap_true. "add the message to the header 

RAISE EXCEPTION TYPE /iwbep/cx_mgw_busi_exception
 EXPORTING message_container = lo_message_container.

Hi,

In OData, you get the error raised by exception is always part of response. header always have the payload details.

if you need in the header, please follow the below code to fill response header.

DATA: ls_header TYPE ihttpnvp.
ls_header-name = 'ZISM_WARN_MSG'.
ls_header-value = iv_message.
set_header( is_header = ls_header ).

Thanks,

Soumya

Thanks @soumya I could set a message using below method.

However the format is a bit different and the messages added will be shown in header only when we don't raise an exception.

So, achieving it without raising exception.
