BOPF是业务对象处理框架（Business Object Processing Framework，以下简称BOPF），SAP有很多标准的BOPF，本例主要是使用CDS创建自开发的BOPF

整体的CDS结构一般做三层，类似于BW，分别是抽取层（View），转换层（Basic），输出层（Consumption），分别对Basis层和Consumption层搭建BOPF框架,Consumption层暴露给Fiori使用

【前期准备】

• HANA数据源表准备好，本例用SAP的航线表
• Eclipse安装好，装好ABAP插件，创建CDS
• WebIDE环境搭建好

 一、创建CDS+BOPF暴露给Fiori

 1.1  创建CDS VIEW抽取层VIEW

@AbapCatalog.sqlViewName: 'ZDDL_P_FLY'
@AbapCatalog.compiler.compareFilter: true
@AbapCatalog.preserveKey: true
@AccessControl.authorizationCheck:  #NOT_REQUIRED
@EndUserText.label: '航班信息抽取层 basis'
define view ZZ_P_FLY as select from spfli {

   key spfli.carrid ,
   key spfli.connid ,
    spfli.countryfr ,
    spfli.cityfrom  ,
    spfli.airpfrom  ,
    spfli.countryto ,
    spfli.cityto    ,
    spfli.airpto ,
    spfli.fltime ,
    spfli.deptime ,
    spfli.arrtime ,
    spfli.distance ,
    spfli.distid ,
    spfli.fltype ,
    spfli.period 
}

 1.2 创建CDS 转换层VIEW( transfer)

       CDS转换层也是主要的逻辑处理部分，抽取层基本不对数据处理，为转换层搭建BOPF框架，激活之后就会产生对应的BOPF（T-code：BOBX） ，之后对BOPF这块详解

@AbapCatalog.sqlViewName: 'ZDDL_I_FLY'
@AbapCatalog.compiler.compareFilter: true
@AbapCatalog.preserveKey: true
@AccessControl.authorizationCheck: #NOT_REQUIRED
@EndUserText.label: '航班信息转换层 transfer'

@ObjectModel:{
    modelCategory: #BUSINESS_OBJECT,
    compositionRoot: true,
    representativeKey: ['carrid','connid'],
    semanticKey: ['carrid','connid'],
    transactionalProcessingEnabled: true,
    writeActivePersistence: 'SPFLI',
    // enable crud
    createEnabled: true,
    updateEnabled: true,
    deleteEnabled: true
}
define view ZZ_I_FLY as select from ZZ_P_FLY  {
   key carrid ,
   key connid ,
       countryfr ,
       cityfrom  ,
       airpfrom  ,
       countryto ,
       cityto    
}

1.3 创建CDS 输出层 VIEW(Consumption)

        CDS 输出层 VIEW指消费层，同样要搭建BOPF框架，但不会产生BOPF对象，这一层主要是把CDS发布成ODATA服务暴露给Fiori调用

@AbapCatalog.sqlViewName: 'ZDDL_C_FLY'
@AbapCatalog.compiler.compareFilter: true
@AbapCatalog.preserveKey: true
@AccessControl.authorizationCheck:  #NOT_REQUIRED
@EndUserText.label: '航班信息输出层 consumption'

@ObjectModel:{
    semanticKey: ['carrid','connid'],
    transactionalProcessingDelegated: true,
    // enable crud
    createEnabled: true,
    updateEnabled: true,
    deleteEnabled: true
}

@UI.headerInfo: {typeName: 'fly', typeNamePlural: 'fly', title: {value: 'carrid'}}

@OData.publish: true
define view ZZ_C_FLY as select from ZZ_I_FLY {
@UI: {
    lineItem: [{ type: #FOR_ACTION, position: 1,
                 dataAction: 'BOPF:SET_CITY',
                 label: 'Set CITY_TO' }],
    identification: [{type: #FOR_ACTION,
                      position: 1,
                      dataAction: 'BOPF:SET_CITY',
                      label: 'Set CITY_TO' }]
    }
    
   key carrid ,
@UI: {
lineItem: [{ position: 20}],
identification: [{position: 20}],
fieldGroup: [{qualifier: 'Basic'}]
} 
   key connid ,
@UI: {
lineItem: [{ position: 30}],
identification: [{position: 30}],
fieldGroup: [{qualifier: 'Basic'}]
} 
   countryfr ,
@UI: {
lineItem: [{ position: 40}],
identification: [{position: 40}],
fieldGroup: [{qualifier: 'Basic'}]
} 
   cityfrom  ,
@UI: {
lineItem: [{ position: 50}],
identification: [{position: 50}],
fieldGroup: [{qualifier: 'Imsg'}]
} 
   airpfrom  ,
@UI: {
lineItem: [{ position: 60}],
identification: [{position: 60}],
fieldGroup: [{qualifier: 'Imsg'}]
}  
   countryto ,
@UI: {
lineItem: [{ position: 70}],
identification: [{position: 70}],
fieldGroup: [{qualifier: 'Imsg'}]
} 
//@ObjectModel.readOnly: true
   cityto   
}

二、BOPF相关开发测试 

以上CDS+BOPF的框架就完成了，接下来是找转换层生成的BOPF（TCODE:BOBF/BOBX）

 

 2.1 BOPF里面ACTION的实现

  method /BOBF/IF_FRW_ACTION~EXECUTE.
    data(lt_DATA) = value ZTZIFLY( ).
    DATA:  ls_msg       TYPE symsg,
          lv_dummy_msg TYPE string.
    "Read UI clicked sale order
    io_read->retrieve(
      exporting
        iv_node                 =  is_ctx-node_key   " BO Node Name
        it_key                  =  it_key            " BO Key
      importing
        et_data                 =  lt_DATA ).   " Data Return Structure

    "Assuming single instance for a action

     LOOP AT lt_DATA assigning field-symbol().

        -CITYTO = 'BOPFCIT'.

        "Now update the BO instance
        io_modify->update(
          exporting
            iv_node           = is_ctx-node_key    " Node
            iv_key            = -key    " Key
            iv_root_key       = -root_key     " NodeID
            is_data           = ref #( -node_data )    " Data
            it_changed_fields = value #(
                                ( ZIF_Z_I_FLY_C=>sc_node_attribute-ZZ_I_FLY-CITYTO ) )
                        ).
     ENDLOOP.
    IF -CARRID = 'AA'.
*      MESSAGE S000(zyk_cm_bus_plan) WITH 'THIS IS ANOTHER!' INTO lv_dummy_msg.
*      MOVE-CORRESPONDING sy TO ls_msg.
*       eo_message->add_message(
*         EXPORTING
*           is_msg       =  ls_msg   " Structure of Message Variables
*           iv_node      =  is_ctx-node_key   " Node Name
*           iv_key       =  -key   " Key
**           iv_lifetime  =  /bobf/cm_frw=>co_lifetime_state
*           ).
*       APPEND VALUE #( key = -key ) TO et_failed_key .
    ENDIF.
    IF eo_message IS BOUND .
      eo_message = /bobf/cl_frw_factory=>GET_MESSAGE( ) .

    ENDIF.
  endmethod.

使用（tcode：BOBT）测试ACTION

2.2 BOPF里面Validations的实现

   Validations和action类似需要创建实施类，Trigger Action勾选Action就会触发校验

2.3 BOPF里面Query的实现

 

三、Fiori测试
