Map Message Container to Message Protocol Format

Context

If a request is successful, warnings and success messages can be returned to the consumer in the new HTTP header SAP-Message. The format of the messages can be either set by the URL option format=json or in case of a modifying request with an empty response by using the request header Accept: application/json.

Example of adding a message in the header SAP-Message:

lo_message_container->add_message(
         iv_msg_type                = /iwbep/cl_cos_logger=>warning
         iv_msg_id                  = /iwbep/cx_tea_business=>team_id_out_of_range-msgid
         iv_msg_number              = /iwbep/cx_tea_business=>team_id_out_of_range-msgno 
         iv_add_to_response_header  = abap_true 
     ).
