Handler not implemented; Method: AUTHORITY_CHECK, Involved Entities: ZSC4_PV_TRAVEL_M

先把 implementation in class zbp_04_dv_travel_m unique; 给注释掉

然后给Travel（旅行）、Booking（预订）和Booking Supplement（预订补充项）三个实体，分别加上 implementation in class

behavior impl ---change

实现类：

bash 复制代码

CLASS lhc_ZSC4_DV_Travel_M DEFINITION INHERITING FROM cl_abap_behavior_handler.
  PRIVATE SECTION.

    METHODS get_authorizations FOR AUTHORIZATION
      IMPORTING keys REQUEST requested_authorizations FOR ZSC4_DV_Travel_M RESULT result.

ENDCLASS.

CLASS lhc_ZSC4_DV_Travel_M IMPLEMENTATION.

  METHOD get_authorizations.
