Adding a new button to Tax Number toolbar in Change Request

Hi All,

My requirement is to add a new button Check VAT on the Tax Numbers section toolbar next to Edit/New.

I need to validate each tax number that user enters from a third party system.

Currently I enhanced the configuration id BS_SP_OVP of component FPM_OVP_COMPONENT.

On the toolbar, i right clicked and said add toolbar element.

I gave a new event id CHECK_VAT to this button.

Saved the enhancement

On the change request screen, I can see the button 'Check VAT', however it is disabled and cannot be clicked. If i right click on my new button, I see technical help corresponding to the New button of SAP.

I have even enhanced the IF_FPM_GUIBB_LIST~GET_DEFINITION method of class CL_BS_BP_GUIBB_TAX_NUMBERS to add my custom event id 'CHECK_VAT' in the ET_ACTION_DEFINITION parameter. However when adding the button, I do not see my custom event id in the drop down list that SAP proposes.

Can someone please guide me with the correct steps to add a button and also where to write logic for this button click.

Also how do i read the tax number data row wise when the button is clicked? If cursor on row 1 and my check button is clicked, i need to read data corresponding to this row from the tax numbers table.

Any suggestions would be highly appreciated.

Thanks and Regards,
