  1. ABAP/4程序员之路——第3天 上海华和得易信息技术有限公司 王勇

  2. 本日学习内容 • BATCH INPUT程序概念和作成 • DIALOG程序初步

  3. Batch Input程序 • Batch Input是一种数据批量输入SAP系统的辅助程序， SAP系统的资料、格式可以通过Batch Input录入SAP系统 • Batch Input的机制是模拟事务处理将数据录入R/3系统 • Batch Input类似SAP的CATT，控制性更好，处理能力更强

  4. Batch Input处理流程 • 分析需要什么样的数据结构 • 建立Batch Input程序 • 处理Batch Input数据 • 分析结果 • 分析错误的Session

  5. 分析数据结构 • 可以通过在屏幕字段上按‘F1’，然后查看其技术信息获得字段信息 • 一般我们通过工具来进行辅助分析： SHDB － Batch Input Transaction Recorder SM35 － Batch Input Monitoring SCAT － Computer Aided Test Tool

  6. SHDB － Batch Input Transaction Recorder

  7. SHDB － Batch Input Transaction Recorder

  8. SHDB － Batch Input Transaction Recorder

  9. SHDB － Batch Input Transaction Recorder

  10. 建立Batch Input程序 …… “创建Batch Input的数据 APPEND BDCDATA. …… “调用事务 CALL TRANSACTION <transaction code> USING <BDCDATA table> MODE <display mode> UPDATE <update mode> MESSAGE INTO <message table> .

  11. 建立Batch Input程序 • BDCDATA的结构

  12. 建立Batch Input程序 • 声明内部BDCDATA的内部表 * 存放Batch Input操作序列的内部表 -------------------------------------* DATA:BEGIN OF BDCDATA OCCURS 0. INCLUDE STRUCTURE BDCDATA. DATA:END OF BDCDATA. • 清空内部表 *&---------------------------------------------------------------------* *& Action : 清空BatchInput操作序列的内部表BDCDATA * *& Input : 无 * *& Output : 无 * *&---------------------------------------------------------------------* FORM BDC_REFRESH. REFRESH BDCDATA. ENDFORM.

  13. 建立Batch Input程序 • 设置屏幕 *&---------------------------------------------------------------------* *& Action : 添加Program/DynPro操作到BatchInput序列的内部表BDCDATA * *& Input : PROGRAM - 程序名（长度为8的字符串） * *& DYNPRO - 画面号 * *& Output : 无 * *&---------------------------------------------------------------------* FORM BDC_DYNPRO USING PROGRAM DYNPRO. CLEAR BDCDATA. BDCDATA-PROGRAM = PROGRAM. BDCDATA-DYNPRO = DYNPRO. BDCDATA-DYNBEGIN = 'X'. APPEND BDCDATA. ENDFORM.

  14. 建立Batch Input程序 • 设置屏幕字段 *&---------------------------------------------------------------------* *& Action : 添加屏幕数据操作到BatchInput序列的内部表BDCDATA * *& Input : FNAM - 屏幕项目名 * *& FVAL - 填写项目值 * *& Output : 无 * *&---------------------------------------------------------------------* FORM BDC_FIELD USING FNAM FVAL. CLEAR BDCDATA. BDCDATA-FNAM = FNAM. BDCDATA-FVAL = FVAL. APPEND BDCDATA. ENDFORM.

  15. 建立Batch Input程序 “调用事务 CALL TRANSACTION <transaction code> USING <BDCDATA table> MODE <display mode> UPDATE <update mode> MESSAGE INTO <message table> . • Display mode A - Display all (Default) E - Display only error N - No Display • Update Mode S - Continue processing when update is completed ( synchronous ) A - Continue processing immediately
