Some SAP clients need extra information added in to a standard SAP process. Here we’ll explore how to add custom fields in the header areas of t-codes FB60 and FV60. FB60 is for posting vendor invoices and FV60 is for parking vendor invoices. In this sample, we’ll be adding in two custom fields.
From research, I found that BAdi BADI_FDCB_SUBBAS01 would work for the initial requirement. I decided to use BADI_FDCB_SUBBAS04 since some of the 01,02s are used by SAP. Go to t-code SE19 to create a BAdi implementation. It’s a classic BAdi rather than a new BAdi. Choose a name and click change. It will ask you to create it and give it the name of the BAdi, which we’d put BADI_FDCB_SUBBAS04.

We get a screen that tells us the two methods that the BAdi has and the name of the implementing class.

The methods should be double clicked and each filled in as follows:
method IF_EX_BADI_FDCB_SUBBAS04~PUT_DATA_TO_SCREEN_OBJECT.
* fill interface attributes from importing paramters
me->if_ex_badi_fdcb_subbas04~invfo = im_invfo.
endmethod.
method IF_EX_BADI_FDCB_SUBBAS04~GET_DATA_FROM_SCREEN_OBJECT.
* fill export parameters from interface attributes
ex_invfo = me->if_ex_badi_fdcb_subbas04~invfo.
endmethod.
On the subscreens tab, we define a program and screen call based on screen 10 since it’s for Vendor Basic Data and we’re adding to vendor screens.

We then must activate the BAdi implementation so that in the Runtime Behavior section, it says Implementation is called. Note: at this point, it will not work. You need to add your new fields to BKPF, VBKPF, and BSEG via append structures. For BKPF, you open the table in SE11. You then click the Append Structure… button at the top and the appends for BKPF will show up. You then click the piece of paper at the top to create.

It will ask you to name your append structure. You fill out the short description, the z fields, give it an enhancement category, and activate. If everything works fine, it will say active. Do this for all three tables.

At this point, it will still not be working. We still have to create our program and screen. Create a program via SE80 and create a custom screen for it. Create the screen however specified and then fill in the flow logic. Note: In PAI, you must put each field that you define after FIELD:

You may wonder how INVFO has these fields, and that’s because it’s also enhanced when you add the append structure to BSEG. On the main program, you’ll fill out all the modules and create some data definitons:

" CHECK_TCODE INPUT
Once this is activated, you will see the screen fields(Event Date and Event Location):

You can also look at any document created and see those fields held in BKPF or VBKPF.
Adding custom fields to many SAP screens follow the same procedure. Knowing how to do this will help you add value to your customer and provide them the ability to have some custom information added in to a standard process.
