TPM deduction management BADI

Hi,

I 'm trying to search for BADI for status change event in TPM deduction management.

For example, there is TPM deduction and user set status to 'settled', it goes to ECC case management

and change the reason code which is the event I defined there.

Is there relative BADI for me to do that? or could you instruct me how I can achieve this?

Thanks.
