SAP VF01/VF02/VF03 Tab Enhancemnt

本文档详细介绍了如何通过创建自定义字段和报告程序来扩展SAP发票处理流程。具体步骤包括为验证断言(VBRK)创建Z字段、在SE38中建立新的报告程序zzinvoice,并在标准程序SAPMV60A中增加两个额外的数据屏幕以供客户使用。此外还提供了修改屏幕显示逻辑的具体ABAP代码示例。

1.Create the Z fields for VBRK.

2.Go to SE38, create report zzinvoice.

 

3. In standard program SAPMV60A, provide 2 screens for customer additional datas, 6001 for header 6002 for details.

 

  loop at screen.

    if screen-name = 'TABSTRIP_TAB06'.


      gs_cust_tab-head_caption = 'TEST'.
      gs_cust_tab-head_program = 'ZZINVOICE'.
      gs_cust_tab-head_dynpro  = '0100'.

      if gs_cust_tab-head_dynpro is not initial.

        screen-active = 1.
        screen-invisible = 0.
        modify screen.
        tabstrip_tab06 = gs_cust_tab-head_caption.
      endif.


    endif.


  endloop.

SAP VF01 and VL01N transaction codes are primarily used in the Logistics Execution and Financial Accounting modules of SAP ERP systems. These transaction codes are essential for processing billing and delivery-related activities in SAP SD (Sales and Distribution) processes. ### Usage of VF01 VF01 is a transaction code used for creating billing documents in SAP. It allows users to generate invoices for delivered goods or services. This transaction is typically used when there is a need to manually process billing documents, especially when automatic billing is not configured or applicable. It supports the creation of various billing types, such as invoices, credit memos, and debit memos. Users can enter billing details like customer information, billing date, and relevant delivery or order numbers. Additionally, VF01 enables the integration of billing data with Financial Accounting (FI) by posting the accounting entries automatically upon saving the document [^1]. ### Usage of VL01N VL01N is a transaction code used for creating delivery documents in SAP SD. It is typically used after a sales order has been created and is ready for shipment. Users can enter details such as the sales order number, delivery date, shipping point, and route. The system then generates a delivery document, which serves as the basis for subsequent processes like picking, packing, and goods issue. VL01N supports the creation of outbound deliveries for various scenarios, including standard deliveries, returns, and cross-company deliveries. It also integrates with Inventory Management (IM) and Warehouse Management (WM) modules to update stock levels and manage logistics operations . ### Integration and Workflow Both VF01 and VL01N play crucial roles in end-to-end business processes. For instance, after a delivery is created using VL01N and goods issue is posted, the system can trigger billing document creation via VF01 based on predefined settings. This ensures seamless flow of data from delivery to billing, maintaining data consistency across modules. Additionally, these transactions can be customized to meet specific business requirements, such as defining default values, enhancing user interfaces, or adding validation checks. ### Example Code for Customization Custom enhancements can be applied to these transactions using ABAP programming or SAP GUI scripting. For example, a custom report can be created to display relevant delivery or billing documents based on specific filters. Below is a sample ABAP code snippet that demonstrates how to retrieve billing documents using the VF01 transaction: ```abap REPORT z_custom_billing_report. DATA: lt_vbrk TYPE TABLE OF vbrk, ls_vbrk TYPE vbrk. SELECT-OPTIONS: s_erdat FOR ls_vbrk-erdat, s_kunnr FOR ls_vbrk-kunnr. START-OF-SELECTION. SELECT * FROM vbrk INTO TABLE lt_vbrk WHERE erdat IN s_erdat AND kunnr IN s_kunnr. IF lt_vbrk IS NOT INITIAL. LOOP AT lt_vbrk INTO ls_vbrk. WRITE: / ls_vbrk-vbeln, ls_vbrk-erdat, ls_vbrk-kunnr. ENDLOOP. ELSE. WRITE: / 'No billing documents found.'. ENDIF. ``` This code retrieves billing documents (stored in the `VBRK` table) based on user input for billing date and customer number, then displays the results in a simple list format. ###
