怎么在SAP ABAP编程环境里创建自己的Z表

本篇内容介绍了"怎么在SAP ABAP编程环境里创建自己的Z表"的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

选中ABAP包，右键创建一个新的Database Table：

维护表名为ZBOOKING:

表实现的源代码：

@EndUserText.label : 'Jerry''s booking'@AbapCatalog.enhancementCategory : #NOT_EXTENSIBLE@AbapCatalog.tableCategory : #TRANSPARENT@AbapCatalog.deliveryClass : #A@AbapCatalog.dataMaintenance : #LIMITEDdefine table zbooking {  key client         : abap.clnt not null;  key booking        : abap.int4 not null;  customername       : abap.char(50);  numberofpassengers : abap.int2;  emailaddress       : abap.char(50);  country            : abap.char(50);  dateofbooking      : timestampl;  dateoftravel       : timestampl;  @Semantics.amount.currencyCode : 'zbooking.currencycode'  cost               : abap.curr(15,2);  currencycode       : abap.cuky;  lastchangedat      : timestampl;}

激活：

下一步，创建一个ABAP类，以代码的方式往Z表里插入数据。

这个ABAP类要实现if_oo_adt_classrun接口，类似Java里的console应用：

完整代码：

CLASS zcl_data_generator DEFINITION  PUBLIC  FINAL  CREATE PUBLIC .  PUBLIC SECTION.    INTERFACES if_oo_adt_classrun.  PROTECTED SECTION.  PRIVATE SECTION.ENDCLASS.CLASS zcl_data_generator IMPLEMENTATION.  METHOD if_oo_adt_classrun~main.    DATA:it_bookings TYPE TABLE OF zbooking.*    read current timestamp    GET TIME STAMP FIELD DATA(zv_tsl).*   fill internal table (itab)    it_bookings = VALUE #(        ( booking  = '1' customername = 'Jerry' numberofpassengers = '3'          emailaddress = 'jerry@sap.com'          country = 'China' dateofbooking ='20190213125959' dateoftravel ='20190213125959'          cost = '546' currencycode = 'EUR' )        ( booking  = '2' customername = 'Tom' numberofpassengers = '1'          emailaddress = 'tom@sap.com'          country = 'USA' dateofbooking ='20190313125959' dateoftravel ='20190313125959' cost = '1373' currencycode = 'USD' lastchangedat = zv_tsl )     ).    DELETE FROM zbooking.    INSERT zbooking FROM TABLE @it_bookings.    SELECT * FROM zbooking INTO TABLE @it_bookings.    out->write( sy-dbcnt ).    out->write( 'data inserted successfully!').  ENDMETHOD.ENDCLASS.

执行这个console应用：

成功插入两条数据：

选中Z表，选择Open with Data Preview:

看到了成功插入的两条数据：
