VT01n,VT02n ...Need user exit or Badi to implement this code :

Question

Hi Experts ,
In VT01n or VT02n transactions , when I give shipping type as 03 (VTTK-VSART) and TransportPlanPt as 4701 (VTTK-TPLST) , the additional data tab  field Suppl. 1 (VTTK-ADD01) must be filled with Z1 value automatically , Even though if the value is not given in additional data tab field Suppl 1 by the user. In which user exit or Badi shall i write my code ???
After saving , I must get Suppl. 1 (VTTK-ADD01) as Z1 ,.
Please suggest User exit or Badi with importing and exporting parameter's as VTTK table or any other solution to achieve this .
Note : Table VTADD01 already has this value Z1 .
Thanks All !!!

There are enhancements you can make for Shipments in transaction CMOD.  Create a new project.  Then you need to add enhancement(s) to the project.  Look at the enhancements starting with V56.  I think enhancement V56USVDP will work for what you want to do.  After the enhancement(s) have been added to the project, then click on the Components button.  You will see a list of function modules.  Sometimes there is documentation available using the blue i button on the screen.  Double click the function module you want to change.  There is also documentation available in the function module sometimes.  Double click the Z include in the function module.  You will have to create the include.  Then you can make the necessary changes in the Z include.  After you have made your code changes, you have to go back to the component screen and activate the enhancement component.  The activate function is in the menu under the project menu.
Hope it helps,
