This explains adding tab in VF01, however you can replace the program name with SAPMV45A instead of SAPMV60A. Discuss with an ABAP'er for further input.
This member of the forum has already been warned not to copy and paste other people's work. Action will now be taken.
Hi Expert,
You can add custom tab to the transaction VF01 by going to T-Code: VF02
Provide the parameters and then Go to Menu -- Goto -- Header -- Header
Step by step how can we add custom tab to the billing header detail;
In order to fulfill the requirement we need a custom sub-screen with some custom fields in that screen.
Steps for creating the custom fields and adding them to the custom sub screen.
1. Creating the Custom fields
a) Create the Z fields to the Table - VBRK, by appending the structure.
Click on Append Structure Button
b) Give a name to the structure for example provide u2018ZZVBRK_APPENDu2019. Enter the fields name which will you need.
Note: the added fields should follow the naming convention that they should start with u2018ZZxxxxxu2019 or u2018YYxxxxxu2019.
c) Save and activate.
2. Creating the z* program and its screen and adding the Z fields on layout.
a) Create a z*program using transaction SE38
Give a name for example ZZBILLHEADER .
b) Create a screen using the transaction SE51.
Program - ZZBILLHEADER
Screen number - 0001
Select Flow logic(Radio Button) and Click on Create Button.
Go to screen layout and get the fields from dictionary on Table - VBRK
The screen in T-Code: VF03 before which is in changeable mode. If you write screen pbo module below code it will be read only.
*Coding
Module status_0001 output.
If sy-tcode = 'VF03'.
loop at screen.
screen-input = '0'.
modify screen.
endloop.
endif.
endmodule.
Save and activate program and screen.
Go to T-Code: VF02,
Provide Billing document and Go to Menu -- System -- Status
Double click Program name - SAPMV60A
Select Screen Folder -- Select Screen - 6001 and
In the u2018cust_head_activateu2019 subroutine(double click), we have to activate - TABSTRIP_TAB06 for customer header tab screen.
3. Steps to write the code in the enhancement spots.
a. First to find the enhancement spots click on the spiral icon in the menu bar, and next click on the Menu -- Edit -- Enhancement operations -- Show implicit enhancement options.
You will see the arrows . On the 5th Line - Right click on the arrow line and click Enhancement Implementation -- Create
4. Give a name for Enhancement point, for example ZZBILLHEADER_ACTIVATE_TAB
Click on Create an Enhancement Button
Click enter and save in a package.
To make use of this logic use enhancement frame work. We have enhancement spots at the begin/end of the subroutine.
5. Steps to write the code in the enhancement spots.
GS_CUST_TAB-HEAD_CAPTION = 'ihracat Ek veriler'.u201Dcustom tab name
GS_CUST_TAB-HEAD_PROGRAM = 'ZZBILLHEADER'.u201Dcustom z* program
GS_CUST_TAB-HEAD_DYNPRO = '0001'u201D custom z* program screen
Activate the enhancement and check in the VF01/ VF02/ VF03 you can find the custom tab with the custom fields. The Data automatically populates to the database table when the data is entered into the Z fields.
